mybatis问题报错BindingException,但是报错name属性,我有写

代码
@Data
public class User {
    private Long id;
    private String name;
    private BigDecimal salary;    
}

public interface UserMapper {
    @Update("update t_user set name = #{name}, salary = #{salary} where id = #{id};")
    void update(User user, Long id);
}

    /* 测试更改 */
    @Test
    public void testUpdate() throws Exception{
        User user = new User();
        user.setId(7L);
        user.setName("小明");
        user.setSalary(new BigDecimal(1));
        
        SqlSession session = MyBatisUtil.getSession();
        UserMapper userMapper = session.getMapper(UserMapper.class);
        userMapper.update(user,1L);
        session.commit();
        session.close();
    }

错误

Error updating database. Cause: org.apache.ibatis.binding.BindingException: Parameter 'name' not found. Available parameters are [arg1, arg0, param1, param2]
The error may exist in com/shan/hello/mapper/UserMapper.java (best guess)
The error may involve com.shan.hello.mapper.UserMapper.update-Inline
The error occurred while setting parameters
SQL: update t_user set name = ?, salary = ? where id = ?;

    void update(User user, Long id);//错误:myBatis默认只能传递一个参数,你可以把id这个参数去掉,
    

    然户再调用方法:userMapper.update(user);
