接口实现类里实现了后续各消费者所调用的各个接口功能，所以事先放出来
数据库操作的mapper文件如下：
/**
* @author wkedong
*
* 2019/1/15
*/
public interface UserMapper {
@Select("SELECT * FROM user")
List getAll();
@Select("SELECT * FROM user WHERE id = #{id}")
UserEntity getOne(int id);
@Insert("INSERT INTO user(name,birthday,address) VALUES(#{name}, #{birthday}, #{address})")
void insert(UserEntity user);
@Update("UPDATE user SET name=#{name},birthday=#{birthday},address=#{address} WHERE id =#{id}")
void update(UserEntity user);
@Delete("DELETE FROM user WHERE id =#{id}")
void delete(int id);
}
分别实现了增删查改基础的实现方法

我使用的是ubuntu13.04系统，在安装nginx的时候遇到如下几个问题，然后找思路解决的，nginx 的下载与安装
wget http://nginx.org/download/nginx-1.0.11.tar.gz
tar zxvf nginx-1.0.11.tar.gz
./configure
make
make install
安装的时候出现
在系统开发过程中，总少不免要自己处理一些异常信息，然后将异常信息变成友好的提示返回到客户端的这样一个过程，之前都是new一个自定义的异常，当然这个所谓的自定义异常也是继承RuntimeException的，但这样往往会造成异常信息说明不一致的情况，所以就想到了用枚举来解决的办法。
1，先创建一个接口，里面有两个方法，一个是getCode, 一个是getMessage
public
