EJB结合struts2创建项目、发布jboss服务器和访问、父类（BaseDaoImpl）的封装
一、环境搭建：
1、准备jboss服务器，将对应数据库的xml配置好放到jboss的发布目录下。
<?xml version="1.0" encoding="UTF-8"?> <datasources> <local-tx-datasource> <jndi-name>MySqlDS</jndi-name> <connection-url>jdbc:mysql://192.168.1.11:3306/test?useUnicode=true&characterEncoding=utf-8</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>root</user-name> <password>root</password> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name> <metadata> <type-mapping>mySQL</type-mapping> </metadata> </local-tx-datasource> </datasources>
2、创建普通的java项目
在该项目的src目录下的META-INF目录下创建persistence.xml文件(名称不能改变)，文件内容如下，发布之后通过jndi名称(MySqlDS)就可以找到数据源。
<?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> <persistence-unit name="UnitMySql"> <jta-data-source>java:/MySqlDS</jta-data-source> <mapping-file>META-INF/mapping.xml</mapping-file> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.show_sql" value="true" /> <!-- <property name="hibernate.format_sql" value="false" /> --> </properties> </persistence-unit> </persistence>
mapping.xml文件里面只有是实体类映射
<?xml version="1.0" encoding="UTF-8"?> <entity-mappings version="1.0" xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd "> <entity class="com.net.entity.User"></entity> .... </entity-mappings>
3、在src目录下创建 jndi.properties
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099
public static Object getEJB(String jndipath) { try { Properties props = new Properties(); props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); props.setProperty("java.naming.provider.url", "localhost:1099"); props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); InitialContext ctx = new InitialContext(props); return ctx.lookup(jndipath); }catch(NamingException ex) { ex.printStackTrace(); } return null; }
二、准备ejb的service层和dao层：
1、父类封装：
public interface BaseDao<T> { public void setOrderBy(String orderBy); public void save(T t) throws DAOException; public void update(T t) throws DAOException; public void delete(T t) throws DAOException; public void delete(Collection<T> list) throws DAOException; public void delete(Serializable id) throws DAOException; public void delete(String[] ids) throws DAOException; public T find(Serializable id) throws DAOException; /** * 获取信息数量 * * @param id * 实体id * @return * @throws DAOException */ public Long findCount() throws DAOException; /** * 获取所有实体类列表 * * @return * @throws DAOException */ public List<T> findAll() throws DAOException; /** * 获取信息分页 * * @param condition * 查询条件 * @param currentPage * 当前页 * @param pageCount * 每页数据行数 * @return 分页信息 * @throws DAOException */ public PageInfo<T> findPageInfo(Integer currentPage, Integer pageCount) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @return 信息列表 * @throws DAOException */ public Long findCountByCondation(String condition) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @return 信息列表 * @throws DAOException */ public List<T> findListByCondation(String condition) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @param currentPage * 当前页 * @param pageCount * 每页数据行数 * @return 信息列表 * @throws DAOException */ public List<T> findListByCondation(String condition, Integer currentPage, Integer pageCount) throws DAOException; /** * 获取信息分页By条件 * * @param condition * 查询条件 * @param currentPage * 当前页 * @param pageCount * 每页数据行数 * @return 分页信息 * @throws DAOException */ public PageInfo<T> findPageInfoByCondation(String condition, Integer currentPage, Integer pageCount) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @return 信息列表 * @throws DAOException */ public Long findCountByNativeCondation(StringBuffer condition) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @return 信息列表 * @throws DAOException */ public List<?> findListByNativeCondation(StringBuffer condition) throws DAOException; /** * 获取信息列表By条件 * * @param condition * 查询条件 * @param currentPage * 当前页 * @param pageCount * 每页数据行数 * @return 信息列表 * @throws DAOException */ public List<?> findListByNativeCondation(StringBuffer condition, Integer currentPage, Integer pageCount) throws DAOException; /** * 获取信息分页By条件 * * @param condition * 查询条件 * @param currentPage * 当前页 * @param pageCount * 每页数据行数 * @return 分页信息 * @throws DAOException */ public PageInfo<?> findPageInfoByNativeCondation(StringBuffer condition, Integer currentPage, Integer pageCount) throws DAOException; public PageInfo<T> findPageInfoBySql(String sql, String countsql, Integer currentPage, Integer pageCount) throws DAOException; public Long findCountByProperties(String condition, Map<String, Object> map) throws DAOException; public List<T> findListByProperties(String condition, Map<String, Object> map) throws DAOException; public List<T> findListByProperties(String condition, Integer currentPage, Integer pageCount, Map<String, Object> map) throws DAOException; public PageInfo<T> findPageInfoByProperties(String condition, Integer currentPage, Integer pageCount, Map<String, Object> map) throws DAOException; public <E> List<E> findListByNativeQuery(String sql, Class<E> clazz) throws DAOException; /** * 查询对象是否存在 * * @param id * 对象id * @return * @throws DAOException */ public boolean isEmpty(String id) throws DAOException; /** * * sql * @param <E> * @param tablename 数据库对应表名 * @param clazz 映射的实体类 * @param sql 查询语句 * @param wheresql 查询语句where后面部分 * @param currentPage 当前页 * @param pageCount 每页数量 * @return * @throws DAOException */ public <E> PageInfo<E> findPageInfoByNativeQuery(Class<E> clazz,String sql, String wheresql, Integer currentPage, Integer pageCount) throws DAOException ; }
public abstract class BaseDaoBean<T> implements BaseDao<T> { protected static final Logger logger = Logger.getLogger(BaseDaoBean.class); protected String orderBy; /** 实体类 */ protected Class<T> entityClass;

}
public class PageInfo<T> implements Serializable, Cloneable { private static final Logger logger = Logger.getLogger(PageInfo.class); private static final long serialVersionUID = -4940465203107135908L; /** 当前页码 */ private Integer currentPage; /** 每页数据行数 */ private Integer pageCount; /** 数据总条数 */ private Integer dataCountMax; /** 最大页码 */ private Integer pageMax; /** 实体集合 */ private List<T> list; /** 是否有上一页 */ private Boolean hasPrev; /** 是否有下一页 */ private Boolean hasNext; /** 显示的页数集合 */ private List<Integer> listPaginDisplay = null; public List<Integer> getListPaginDisplay() { return listPaginDisplay; } public void setListPaginDisplay(List<Integer> listPaginDisplay) { this.listPaginDisplay = listPaginDisplay; } public PageInfo() { } @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } /** * @param currentPage * 当前页码 * @param pageCount * 每页数据行数 * @param dataCountMax * 数据总条数 */ public PageInfo(Integer currentPage, Integer pageCount, Integer dataCountMax) { this.currentPage = currentPage; this.pageCount = pageCount; this.dataCountMax = dataCountMax; this.setParameters(); } /** * @param currentPage * 当前页码 * @param pageCount * 每页数据行数 * @param dataCountMax * 数据总条数 * @param list * 分页后list */ public PageInfo(Integer currentPage, Integer pageCount, Integer dataCountMax, List<T> list) { this.currentPage = currentPage; this.pageCount = pageCount; this.dataCountMax = dataCountMax; this.setParameters(); this.list = list; } /** 重新加载数据信息 */ public void setParameters() { if (currentPage == null) { currentPage = 1; } if (pageCount == null || pageCount < 1) { logger.warn("pageCount = 0, setPageCount=100"); pageCount = 100; } if (dataCountMax == null) { dataCountMax = 10; } this.pageMax = dataCountMax % pageCount == 0 ?

可以实现多表查询
public PageInfo findPageInfoBySql(String sql,String countsql, Integer currentPage, Integer pageCount) throws DAOException{ Long count = (Long) entityManager.createQuery(countsql).getSingleResult(); if (orderBy != null && !orderBy.isEmpty()) { sql+=" ORDER BY " + orderBy; } Query query = entityManager.createQuery(sql); if (currentPage != null && pageCount != null) { query.setFirstResult((currentPage - 1) * pageCount); query.setMaxResults(pageCount); } return new PageInfo(currentPage, pageCount, count.intValue(),query.getResultList()); }
public class PageInfo implements Serializable { private static final Logger logger = Logger.getLogger(PageInfo.class); private static final long serialVersionUID = -4940465203107135908L; /** 当前页码 */ private Integer currentPage; /** 每页数据行数 */ private Integer pageCount; /** 数据总条数 */ private Integer dataCountMax; /** 最大页码 */ private Integer pageMax; /** 实体集合 */ private List<?> list; /** 是否有上一页 */ private Boolean hasPrev; /** 是否有下一页 */ private Boolean hasNext; private List<?> listPaginDisplay = null; public List<?> getListPaginDisplay() { return listPaginDisplay; } public void setListPaginDisplay(List listPaginDisplay) { this.listPaginDisplay = listPaginDisplay; } public PageInfo() { } /** * @param currentPage * 当前页码 * @param pageCount * 每页数据行数 * @param dataCountMax * 数据总条数 */ public PageInfo(Integer currentPage, Integer pageCount, Integer dataCountMax) { this.currentPage = currentPage; this.pageCount = pageCount; this.dataCountMax = dataCountMax; this.setParameters(); } /** * @param currentPage * 当前页码 * @param pageCount * 每页数据行数 * @param dataCountMax * 数据总条数 * @param list * 分页后list */ public PageInfo(Integer currentPage, Integer pageCount, Integer dataCountMax, List<?> list) { this.currentPage = currentPage; this.pageCount = pageCount; this.dataCountMax = dataCountMax; this.setParameters(); this.list = list; } /** 重新加载数据信息 */ public void setParameters() { if (currentPage == null) { currentPage = 1; } if (pageCount == null || pageCount < 1) { logger.warn("pageCount = 0, setPageCount=100"); pageCount = 100; } if (dataCountMax == null) { dataCountMax = 10; } this.pageMax = dataCountMax % pageCount == 0 ? (dataCountMax / pageCount) : (dataCountMax / pageCount + 1); if (currentPage > pageMax) { currentPage = pageMax; } this.hasPrev = currentPage > 1 ? true : false; this.hasNext = pageMax > currentPage ? true : false; } /** * @return the currentPage */ public Integer getCurrentPage() { return currentPage; } /** * @param currentPage * the currentPage to set */ public void setCurrentPage(Integer currentPage) { this.currentPage = currentPage; // 重新加载数据信息 this.setParameters(); } /** * @return the pageCount */ public Integer getPageCount() { return pageCount; } /** * @param pageCount * the pageCount to set */ public void setPageCount(Integer pageCount) { this.pageCount = pageCount; // 重新加载数据信息 this.setParameters(); } /** * @return the pageMax */ public Integer getPageMax() { return pageMax; } /** * @param pageMax * the pageMax to set */ public void setPageMax(Integer pageMax) { this.pageMax = pageMax; } /** * @return the list */ public List<?> getList() { return list; } /** * @param list * the list to set */ public void setList(List<?> list) { this.list = list; } /** * @return the hasPrev */ public Boolean getHasPrev() { return hasPrev; } /** * @param hasPrev * the hasPrev to set */ public void setHasPrev(Boolean hasPrev) { this.hasPrev = hasPrev; } /** * @return the hasNext */ public Boolean getHasNext() { return hasNext; } /** * @param hasNext * the hasNext to set */ public void setHasNext(Boolean hasNext) { this.hasNext = hasNext; } /** * @return the dataCountMax */ public Integer getDataCountMax() { return dataCountMax; } /** * @param dataCountMax * the dataCountMax to set */ public void setDataCountMax(Integer dataCountMax) { this.dataCountMax = dataCountMax; } }
2、dao接口及实现：
public interface PersonDao extends BaseDao<Person> { } public interface PersonDaoLocal extends PersonDao { } public interface PersonDaoRemote extends PersonDao { }
@Stateless @Local(PersonDaoLocal.class)//dao层实现用本地接口 public class PersonDaoImpl extends BaseDaoBean<Person> implements PersonDaoLocal,PersonDaoRemote{ @Override @PersistenceContext(unitName = "UnitMySql") public void setEntityManager(EntityManager entityManager) { this.entityManager = entityManager; } }
3、service接口及实现：
public interface PersonService extends BaseService<Person> { public void update() throws ServiceException; }
//无状态bean，本地接口和远程接口 jndi名称 @Stateless @Local(PersonServiceLocal.class) @LocalBinding(jndiBinding = "PersonServiceBean/local") @Remote(PersonServiceRemote.class) @RemoteBinding(jndiBinding = "PersonServiceBean/remote") public class PersonServiceImpl implements PersonServiceLocal,PersonServiceRemote { @EJB private PersonDaoLocal perosnDaoLocal; //通过ejb注入方式将dao层注入到service中 }
4、调用Service
public class ActionSupportBase extends ActionSupport implements SessionAware, RequestAware, ServletResponseAware, ServletRequestAware, ApplicationAware { private static final long serialVersionUID = -4065551378754830182L; private static final Logger logger = Logger.getLogger(ActionSupportBase.class); protected static final String STATUS = "status"; protected static final String MESSAGE = "message"; protected static final String INFO = "info"; protected static final String Y = "y"; protected static final String N = "n"; protected static final String MODIFY = "modify"; protected static final String DETAIL = "detail"; protected static final String SAVE_SUCCESS = "保存成功"; protected static final String MODIFY_SUCCESS = "修改成功!"; protected static final String DELETE_SUCCESS = "删除成功"; protected String systemName = ServletActionContext.getServletContext().getInitParameter(ConstUtil.SYSTEMNAME); protected Map<String, Object> jsonMap = new HashMap<String, Object>(); protected Map<String, Object> application; protected Map<String, Object> session; protected Map<String, Object> request; protected HttpServletResponse servletResponse; protected HttpServletRequest servletRequest; protected static Context context = null; public ActionSupportBase() { initContext(); } protected void initContext() { try { if (context == null) { context = new InitialContext(); } } catch (NamingException e) { logger.warn(e); } } /** * 将一个字符串输出到浏览器 * * @author 李斌 * @param json * 字符串 */ protected void writeJson(String json) { PrintWriter pw = null; try { servletResponse.setContentType("text/plain;charset=UTF-8"); pw = servletResponse.getWriter(); pw.write(json); pw.flush(); pw.close(); } catch (IOException e) { e.printStackTrace(); } finally { if (pw != null) { pw.close(); } } } public Map<String, Object> getApplication() { return application; } public void setApplication(Map<String, Object> application) { this.application = application; } public Map<String, Object> getSession() { return session; } public void setSession(Map<String, Object> session) { this.session = session; } public Map<String, Object> getRequest() { return request; } public void setRequest(Map<String, Object> request) { this.request = request; } public Map<String, Object> getJsonMap() { return jsonMap; } public void setJsonMap(Map<String, Object> jsonMap) { this.jsonMap = jsonMap; } public HttpServletResponse getServletResponse() { return servletResponse; } public void setServletResponse(HttpServletResponse servletResponse) { this.servletResponse = servletResponse; } public HttpServletRequest getServletRequest() { return servletRequest; } public void setServletRequest(HttpServletRequest servletRequest) { this.servletRequest = servletRequest; } }
Context context = new InitialContext(); private PersonServiceRemote service = (PersonServiceRemote) context.lookup("PersonServiceBean/remote");
三、创建web项目
1、需要引入jboss的jboss-4.2.3.GA\client目录下的jar文件。
2、在WEB-INF文件夹下创建jboss-web.xml文件，它用于设置发布到jboss上项目的根路径。
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE jboss-web PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN" "http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd"> <jboss-web> <context-root>/</context-root> <virtual-host>self.net.cn</virtual-host> </jboss-web>
3、如果要打包成ear项目，通过ant文件，在ear项目下需要创建一个META-INF文件夹，然后再META-INF文件夹下创建application.xml文件。
<?xml version="1.0" encoding="ASCII"?> <application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:application="http://java.sun.com/xml/ns/javaee/application_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd" version="5"> <display-name>my</display-name> <module> <ejb>myejb.jar</ejb> </module> <module> <web> <web-uri>myweb.war</web-uri> <context-root>/</context-root> </web> </module> </application>
四、发布项目
1、可以将项目打成war包或（ear）发布到jboss服务器上，可以发布到“ jboss-4.2.3.GA\server\all\deploy ”目录下。
2、访问资源文件：localhost:8080/项目名称/资源文件
3、访问action：localhost:8080/项目名称/struts包命名空间/action
4、http://127.0.0.1：8080/jbossws/services 查看webservice的发布情况
5、127.0.0.1/jmx-console 查看jboss服务
