< insert id = "addRoleModule" parameterType = "java.util.List" >
     INSERT INTO T_P_ROLE_MODULE (ROLE_ID, MODULE_ID)
     VALUES < foreach collection = "list" item = "item" index = "index" 
     separator = ","
     ( #{item.roleId}, #{item.moduleId})

< insert id = "addRoleModule" parameterType = "java.util.List" >
     INSERT INTO T_P_ROLE_MODULE (ROLE_ID, MODULE_ID)

oracle和mysql数据库的批量update在mybatis中配置不太一样:

oracle数据库:

< update id= "batchUpdate"  parameterType= "java.util.List" >
      
        <foreach collection= "list" item= "item" index = "index" open = "begin" close = "end;" separator= ";" >
                 update test
                 < set >
                   test=${item.test}+1
                 </ set >
                 where id = ${item.id}
        </foreach>
          
     </ update >

mysql数据库:

mysql数据库采用一下写法即可执行,但是数据库连接必须配置:&allowMultiQueries=true

例如:jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&amp;characterEncoding=UTF-8&allowMultiQueries=true

                 update test
                 < set >
                   test=${item.test}+1
                 </ set >
                 where id = ${item.id}
          </foreach>
          
     </ update >
