mybatis 插入或者更新

  
    
    
      select count(*) as count from phone2email where phone = #{phone,jdbcType=VARCHAR}
    

    
    
      update phone2email set email=#{email,jdbcType=VARCHAR} where phone = #{phone,jdbcType=VARCHAR}
    

    
    
      insert into phone2email(phone,email)
      values(#{phone,jdbcType=VARCHAR},#{email,jdbcType=VARCHAR})
    

  

这里的count要有setter方法，也就是要作为Phone2Email（对象）的属性：

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class Phone2Email {
    private Integer id;

    private String phone;

    private String email;

    private int count;


 }

如果没有则会报错：

Caused by: org.apache.ibatis.executor.ExecutorException: No setter found for the keyProperty 'count' in com.sa.pojo.Phone2Email.
