SSM整合---环境搭建
l 查询所有用户的信息，保存用户信息
1.pom.xml配置项目所需的jar包
<dependencies> <dependency> <groupId>junitgroupId> <artifactId>junitartifactId> <version>4.11version> dependency> <dependency> <groupId>ch.qos.logbackgroupId> <artifactId>logback-classicartifactId> <version>1.1.1version> dependency> <dependency> <groupId>mysqlgroupId> <artifactId>mysql-connector-javaartifactId> <version>5.1.37version> <scope>runtimescope> dependency> <dependency> <groupId>c3p0groupId> <artifactId>c3p0artifactId> <version>0.9.1.2version> dependency> <dependency> <groupId>org.mybatisgroupId> <artifactId>mybatisartifactId> <version>3.3.0version> dependency> <dependency> <groupId>org.mybatisgroupId> <artifactId>mybatis-springartifactId> <version>1.2.3version> dependency> <dependency> <groupId>taglibsgroupId> <artifactId>standardartifactId> <version>1.1.2version> dependency> <dependency> <groupId>jstlgroupId> <artifactId>jstlartifactId> <version>1.2version> dependency> <dependency> <groupId>com.fasterxml.jackson.coregroupId> <artifactId>jackson-databindartifactId> <version>2.5.4version> dependency> <dependency> <groupId>javax.servletgroupId> <artifactId>javax.servlet-apiartifactId> <version>3.1.0version> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-coreartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-beansartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-contextartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-jdbcartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-txartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-webartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-webmvcartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>org.springframeworkgroupId> <artifactId>spring-testartifactId> <version>4.1.7.RELEASEversion> dependency> <dependency> <groupId>redis.clientsgroupId> <artifactId>jedisartifactId> <version>2.7.3version> dependency> <dependency> <groupId>com.dyuproject.protostuffgroupId> <artifactId>protostuff-coreartifactId> <version>1.0.8version> dependency> <dependency> <groupId>com.dyuproject.protostuffgroupId> <artifactId>protostuff-runtimeartifactId> <version>1.0.8version> dependency> <dependency> <groupId>commons-collectionsgroupId> <artifactId>commons-collectionsartifactId> <version>3.2version> dependency> <dependency> <groupId>aopalliancegroupId> <artifactId>aopallianceartifactId> <version>1.0version> dependency> <dependency> <groupId>org.aspectjgroupId> <artifactId>aspectjweaverartifactId> <version>1.9.2version> dependency> <dependency> <groupId>org.aspectjgroupId> <artifactId>aspectjrtartifactId> <version>1.9.3version> dependency> <dependency> <groupId>org.aspectjgroupId> <artifactId>aspectjweaverartifactId> <version>1.9.4version> dependency> dependencies>
2.web.xml文件配置前端控制器，过滤器（处理中文乱码）和监听器（监听项目启动）
<web-app> <display-name>Archetype Created Web Applicationdisplay-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class> listener> <context-param> <param-name>contextConfigLocationparam-name> <param-value>classpath:applicationContext.xmlparam-value> context-param> <filter> <filter-name>encodingFilterfilter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class> <init-param> <param-name>encodingparam-name> <param-value>UTF-8param-value> init-param> <init-param> <param-name>forceEncodingparam-name> <param-value>trueparam-value> init-param> filter> <filter-mapping> <filter-name>encodingFilterfilter-name> <url-pattern>/*url-pattern> filter-mapping> <servlet> <servlet-name>SpringMVCservlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class> <init-param> <param-name>contextConfigLocationparam-name> <param-value>classpath:springmvc.xmlparam-value> init-param> <load-on-startup>1load-on-startup> servlet> <servlet-mapping> <servlet-name>SpringMVCservlet-name> <url-pattern>/url-pattern> servlet-mapping> web-app>
3.创建springmvc.xml文件，进行spring与springmvc的整合配置
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
">
<context:component-scan base-package="com.ssm.controller">context:component-scan>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/">property>
<property name="suffix" value=".jsp">property>
bean>
<mvc:resources mapping="/css/**" location="/css/">mvc:resources>
<mvc:resources mapping="/images/**" location="/images/">mvc:resources>
<mvc:resources mapping="/js/**" location="/js/">mvc:resources>
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
beans>
4.创建applicationContext.xml文件，进行spring与mybatis的整合配置
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

5.创建与数据库表对应的实体类，实体类属性与表中对应
package com.ssm.entity; public class User { private int id; private String username; private String password; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @Override public String toString() { return "User{" + "id=" + id + ", username='" + username + '\'' + ", password='" + password + '\'' + '}'; } }
6.创建dao层接口
package com.ssm.dao; import com.ssm.entity.User; import org.springframework.stereotype.Repository; import java.util.List; @Repository public interface UserDao { //查询所有用户信息 public ListfindAll(); //保存用户信息 public void save(User user); }
7.创建dao层的xml文件，用于写sql语句，文件路径与dao接口的路径对应，文件名与dao接口名一样
xml version="1.0" encoding="UTF-8" ?>
DOCTYPEmapper
PUBLIC"-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.ssm.dao.UserDao">
<select id="findAll" resultType="com.ssm.entity.User">
select * from user
select>
<insert id="save" parameterType="com.ssm.entity.User">
insert into user(username,password) values(#{username},#{password})
insert>
mapper>
8.创建service层，创建service层的接口
package com.ssm.service; import com.ssm.entity.User; import org.springframework.stereotype.Service; import java.util.List; @Service public interface UserService { //查询所有用户信息 public ListfindAll(); //保存用户信息 public void save(User user); }
9.创建service层的实现类
package com.ssm.service.Impl; import com.ssm.dao.UserDao; import com.ssm.entity.User; import com.ssm.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public ListfindAll() { System.out.println("业务层：查询所有用户信息"); return userDao.findAll(); } @Override public void save(User user) { System.out.println("业务层：添加用户信息"); userDao.save(user); } }
10.创建controller层，创建类
package com.ssm.controller; import com.ssm.entity.User; import com.ssm.service.Impl.UserServiceImpl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import java.util.List; @Controller @RequestMapping("/UserController") public class UserController { @Autowired private UserServiceImpl userService; @RequestMapping("/findAll") public ModelAndView findAll(){ ModelAndView modelAndView=new ModelAndView(); Listlist=userService.findAll(); modelAndView.addObject("list",list); for(User u:list){ System.out.println(u); } modelAndView.setViewName("list"); System.out.println("controllrt中的findAll方法"); return modelAndView; } @RequestMapping("/save") public String save(User user){ userService.save(user); return "list"; } }
11.编写index.jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Titletitle> head> <body> <a href="UserController/findAll">跳转a> <form action="UserController/save" method="post"> <input type="text" name="username"> <input type="text" name="password"> <input type="submit" > form> body> html>
12.编写list.jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@page isELIgnored="false" %> <html> <head> <title>Titletitle> head> <body> ${list} body> html>
