Maven项目往数据库插入数据显示成功但是表中都是null

Question

Maven项目用jdk动态代理模式向数据库插入数据，显示执行成功但是数据库表中都是null

这是接口中定义的插入方法

int insert(Users users);

这是mapper.xml文件中的insert语句
Users类型已经注册了别名

<insert id="insert" parameterType="users">
        insert into t_users(username,birthday,sex,address)
        values(username=#{userName},birthday=#{birthday},sex=#{sex},address=#{address})
 </insert>

这是实体类的实例变量，构造函数提供了无参,全参,除去id之外4个参数的三种

public class Users {
    private Integer id;
    private String userName;
    private Date birthday;
    private String sex;
    private String address;

测定方法的代码如下

public class MyTest {
    SqlSession sqlSession;
    UsersMapper uMapper;
    SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd");
    @Before
    public void openSqlSession() throws IOException {
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        sqlSession = factory.openSession();
        uMapper = sqlSession.getMapper(UsersMapper.class);
    }
    @After
    public void closeSqlSession(){
        sqlSession.close();
    }
   public void testInsert() throws ParseException {
        Users users = new Users("ssss",new Date(),"2","上海市");
        Integer num =uMapper.insert(users);
        sqlSession.commit();
    }
}
