Mybatis利用ResultMap自定义映射案例

package org.xsx.entity;

public class Emp2 {
private Integer eid;
private String ename;
private Integer eage;
public Integer getEid() {
return eid;
}
public void setEid(Integer eid) {
this.eid = eid;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
public Integer getEage() {
return eage;
}
public void setEage(Integer eage) {
this.eage = eage;
}

}

<resultMap type="org.xsx.entity.Emp2" id="empMap">
<result property="eid" column="id" jdbcType="INTEGER" javaType="int" />
<result property="ename" column="name" jdbcType="VARCHAR" javaType="string" />
<result property="eage" column="age" jdbcType="INTEGER" javaType="int" />
</resultMap>

<select id="findAll1" resultMap="empMap">
select id,name,age from emp
</select>

public List<Emp2> findAll1();

package org.xsx.test;

import java.util.List;
