• mybatis 中文做参数报错


      一个简单的查询,如果参数中有中文。如下:

    <select id="xxxx" resultType="hashmap">
        select * from talbe_a a where  a.kpeople = ${name}
    </select>

    报错:

    org.apache.ibatis.exceptions.PersistenceException: 
    ### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: ORA-00904: "萧亚轩": 标识符无效
    ...

    Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "萧亚轩": 标识符无效
    ....

    mybatis sql日志:

    18:06:36,192 DEBUG JdbcTransaction:47 - Openning JDBC Connection
    18:06:36,830 DEBUG PooledDataSource:47 - Created connection 1459361227.

    18:06:36,961 DEBUG queryrealactormediatop:47 - ==> Parameters: 

    注意:“萧亚轩”两边没有单引号,不是“?”的占位符,参数列表里面是没有值。

    修改其实很简单:

    v1:换$ 为#

    <select id="xxxx" resultType="hashmap">
        select * from talbe_a a where  a.kpeople = #{name}
    </select>

    v2:添加 ‘’ 单引号

    <select id="xxxx" resultType="hashmap">
        select * from talbe_a a where  a.kpeople = ‘${name}‘
    </select>

    #只会当成个字符串

    $就不一定是字符串,或者其他类型
