public void testParamModel(){
Tone t1 = new Tone();
t1.setAdd("address1");
t1.setPhone("phone");
Ttwo t2 = new Ttwo();

s.setUsername("username");
List<String> l = sysService.testRun07(s);
}

service !!!!!!!!!

public List<String> testRun07(SysU s){

List<String> l = sysUMapper.testParamModel2(s);

return l;
}

mapper.java

public List<String> testParamModel2(@Param("sysu") SysU sysu);

mapper.xml

<select id="testParamModel2" resultType="java.lang.String">
　　select username from testuser
　　　　<where>
　　　　　　address = #{sysu.t1.add}
　　　　</where>
</select>

注意   获取的 t1  与 add  分别为 对象中成员变量的名字   通过 getter方法名字来获取数值
