已解决:mybatis报错:org.apache.ibatis.reflection.ReflectionException: There is no getter for property name

mybatis模糊查询姓名时报错

 报错内容:org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'name' in 'class java.lang.String'
### Cause: org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'name' in 'class java.lang.String'

mapper文件查询代码:

    <select id="getByName" parameterType="string" resultType="users">
        select id,username,birthday,sex,address
        from users where username like '%${name}%'
    </select>

测试类代码:

    @Test
    public void testGetByName(){
        List<Users>list = uMapper.getByName("小");
        list.forEach(users -> System.out.println(users));

解决方法:

方法一:将  '%${name}%' 变为 '%${_parameter}%'

修改后的代码

    <select id="getByName" parameterType="string" resultType="users">
        select id,username,birthday,sex,address
        from users where username like '%${_parameter}%'
    </select>

方法二:优化后的迷糊查询: '%${name}%' 变为

concat('%',#{name},'%')

修改后的代码:

    <select id="getByNameGood" parameterType="string" resultType="users">
        select id,username,birthday,sex,address from users where username like concat('%',#{name},'%')
    </select>

问题解决。
