Mapped Statements collection alr

集成Mybatis莫名其妙报了这错，下面是我的测试代码：

    @Select("select * from user where username = #{username}")
    @Results({
            @Result(property = "username", column = "user_name"),
            @Result(property = "password", column = "password")
    })
    User getUser(String username);

    @Select("select * from user where id = #{id}")
    @ResultMap("BaseResultMap")
    User getUser(int id);

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.techsun.springheart.mapper.UserMapper">

    <resultMap id="BaseResultMap" type="com.techsun.springheart.model.User">
        <id column="id" jdbcType="BIGINT" property="id"></id>
        <result column="username" jdbcType="VARCHAR" property="username"/>
        <result column="password" jdbcType="VARCHAR" property="password"/>
    </resultMap>

......
</mapper>

乍一看没啥问题啊，报的错误看起来像是id重复之类的，网上大部分的解释也是id重复巴拉巴拉，其实，这里跟id没毛关系，是因为我在上面定义了两个重名，返回值还一样的方法

User getUser(....)

把其中一个改下名字就okay了。
