上面是报的错

<insert id="insertSelective" parameterType="com.miaoshaproject.dataObject.UserPasswordDO">
  insert into user_password
  <trim prefix="(" suffix=")" suffixOverrides=",">
    <if test="id != null">
      id,
    </if>
    <if test="encrptPassword != null">
      encrpt_password,
    </if>
    <if test="userId != null">
      user_id,
    </if>
  </trim>
  <trim prefix="values (" suffix=")" suffixOverrides=",">
    <if test="id != null">
      #{id,jdbcType=INTEGER},
    </if>
    <if test="encrptPassword != null">
      #{encrptPassword,jdbcType=VARCHAR},
    </if>
    <if test="userId != null">
      #{userId,jdbcType=INTEGER},
    </if>
  </trim>
</insert>

上面是我对应的mappper里面的sql语句

这个是本人创建的数据库

class UserPasswordDO {
    private Integer id;

    private String encrptPassword;

    private Integer userId;

    public UserPasswordDO(Integer id, String encrptPassword, Integer userId) {
        this.id = id;
        this.encrptPassword = encrptPassword;
        this.userId = userId;
    }

    public UserPasswordDO() {
        super();
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getEncrptPassword() {
        return encrptPassword;
    }

    public void setEncrptPassword(String encrptPassword) {
        this.encrptPassword = encrptPassword == null ? null : encrptPassword.trim();
    }

    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }
}

这是对应的dataObjext 

难受啊
