## 异常分析 ##

#### mapper.xml导致的错误地方 ####

<insert id="addRoles">
    		<foreach collection="data.ids" item="id" separator=";">
    			INSERT INTO t_user_role(userid,roleid)VALUES(#{userId},#{id})
    		</foreach>
      </insert>

异常中说

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO t_user_role(userid,roleid)VALUES(1,3)

**首先觉得是 sql语句的问题，但是用sqlyog测试发现没有问题**  
**后来发现是数据库对多个语句拼在一起的操作不支持问题**

# 解决办法 #

在jdbcUrl中加入allowMultiQueries=true即可解决

jdbc.url=jdbc:mysql://localhost:3306/atcrowdfunding?allowMultiQueries=true&rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf8
