ibatis简单运行

我所有的代码都在ibatis包下，包括类和配置文件 

代码

   
     

    
      
    
      <?
    
      xml version="1.0" encoding="utf-8"
    
      ?>
    
      

    
      <!
    
      DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
 "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"
    
      >
    
      

    
      <
    
      sqlMapConfig
    
      >
    
      
 
    
      <
    
      settings 
    
      cacheModelsEnabled
    
      ="false"
    
       enhancementEnabled
    
      ="false"
    
      
 lazyLoadingEnabled
    
      ="false"
    
       maxRequests
    
      ="3000"
    
       maxSessions
    
      ="3000"
    
      
 maxTransactions
    
      ="3000"
    
       useStatementNamespaces
    
      ="false"
    
       
    
      />
    
      
 
    
      <
    
      transactionManager 
    
      type
    
      ="JDBC"
    
      >
    
      
 
    
      <
    
      dataSource 
    
      type
    
      ="simple"
    
      >
    
      
 
    
      <
    
      property 
    
      name
    
      ="JDBC.Driver"
    
      
 value
    
      ="com.mysql.jdbc.Driver"
    
       
    
      />
    
      
 
    
      <
    
      property 
    
      name
    
      ="JDBC.ConnectionURL"
    
      
 value
    
      ="jdbc:mysql://localhost:3306/test"
    
       
    
      />
    
      
 
    
      <
    
      property 
    
      name
    
      ="JDBC.Username"
    
       value
    
      ="root"
    
       
    
      />
    
      
 
    
      <
    
      property 
    
      name
    
      ="JDBC.Password"
    
       value
    
      ="******"
    
       
    
      />
    
      
 
    
      </
    
      dataSource
    
      >
    
      
 
    
      </
    
      transactionManager
    
      >
    
      
 
    
      <
    
      sqlMap 
    
      resource
    
      ="ibatis/user.xml"
    
       
    
      />
    
      

    
      </
    
      sqlMapConfig
    
      >
   
     

 

接下去是user.xml

代码

   
     

    
      
    
      <?
    
      xml version="1.0" encoding="UTF-8"
    
      ?>
    
      


    
      <!

      <
    
      sqlMap 
    
      namespace
    
      ="User"
    
      >
    
      

 
    
      <
    
      typeAlias 
    
      alias
    
      ="user"
    
       type
    
      ="ibatis.User"
    
       
    
      />
    
      
 
    
      <
    
      select 
    
      id
    
      ="getUser"
    
       resultClass
    
      ="user"
    
       parameterClass
    
      ="java.lang.String"
    
      >
    
      
 select * from user where name like '%$name$%';
 
    
      </
    
      select
    
      >
    
      
 
 
    
      <
    
      select 
    
      id
    
      ="getAllUser"
    
       resultClass
    
      ="user"
    
      >

      </
    
      select

      </
    
      sqlMap
    
      >
   
     

 

代码

   
     

    
      
    
      package
    
       ibatis;


    
      import
    
       java.io.IOException;

    
      import
    
       java.io.Reader;

    
      import
    
       java.sql.SQLException;

    
      import

      import
    
       com.ibatis.sqlmap.client.SqlMapClient;

    
      import
    
       com.ibatis.sqlmap.client.SqlMapClientBuilder;


    
      public
    
       
    
      class
    
       IbatisDemo {
 
    
      public
    
       
    
      static
    
       
    
      void
    
       main(String[] args) 
    
      throws
    
       IOException, SQLException {
 BasicConfigurator.configure();
 String resource 
    
      =
    
       
    
      "
    
      ibatis/sqlmap.xml
    
      "
    
      ;
 Reader reader 
    
      =
    
       Resources.getResourceAsReader(resource);

 SqlMapClient sqlMap 
    
      =
    
       SqlMapClientBuilder.buildSqlMapClient(reader);
 List list 
    
      =
    
       sqlMap.queryForList(
    
      "
    
      getUser
    
      "
    
      , 
    
      "
    
      sa
    
      "
    
      );
 System.out.println(list.size());
 
 list 
    
      =
    
       sqlMap.queryForList(
    
      "
    
      getAllUser
    
      "
    
      );
 System.out.println(list.size());
 }
}

   
     

 User.java类我就不贴了，一个只有两个private属性的bean，很简单的run就可以得出结果，这也是最简单的ibatis应用了
