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&characterEncoding=UTF-8&allowMultiQueries=true
<update id="batchUpdate"  parameterType="java.util.List">
	 
	      <foreach collection="list" item="item" index="index" open="" close="" separator=";">
				update test 
				<set>
				  test=${item.test}+1
				</set>
				where id = ${item.id}
		 </foreach>
		 
    </update>
