前期准备
- 一台云服务器
- 云服务器安装MySQL8.x
- 云服务器安装jdk8
数据库初始化
由于本项目使用的是springdatajpa,所以不需要我们手动建表,只需要建数据库启动项目,会自动建表
CREATE DATABASE daily_weather;
这里提供数据库备份

项目结构介绍
- advice : 负责统一封装处理前端返回数据格式
- common : 统一结果封装
- config: 项目配置
- domain: 实体类
- enums: 服务状态枚举类
- exception: 异常处理和自定义异常
- job: 定时任务
- remote: 第三方接口调用,使用openfeign
- repository: 数据库操作层,dao/mapper层
- rest: 视图控制层
- service: 业务处理层
统一结果封装
注意返回String类型需要特殊处理
package com.zhao.wechat.advice;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.zhao.wechat.common.Result;
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.MethodParameter;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.server.ServerHttpRequest;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice;
/**
* 对前端响应结果统一封装
*/
@Slf4j
@RestControllerAdvice(basePackages = {
"com.zhao.wechat.rest"})
public class ApiResponseAdvice implements ResponseBodyAdvice<Object> {
/**
* 打印统一请求响应规范
*/
ApiResponseAdvice(){
log.info("启动请求统一响应规范... ...");
}
/**
* 判断是否需要对返回值进行封装
* @param returnType the return type
* @param converterType the selected converter type
* @return
*/
@Override
public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
// 如果返回的结果是Result.class类型就不用封装
if (returnType.getParameterType().equals(Result.class)){
return false;
}
return true;
}
/**
* 对返回前端的值统一封装
* @param body the body to be written
* @param returnType the return type of the controller method
* @param selectedContentType the content type selected through content negotiation
* @param selectedConverterType the converter type selected to write to the response
* @param request the current request
* @param response the current response
* @return
*/
@Override
public Object beforeBodyWrite(Object body,
MethodParameter returnType,
MediaType selectedContentType,
Class<? extends HttpMessageConverter<?>> selectedConverterType,
ServerHttpRequest request,
ServerHttpResponse response) {
if (returnType.getParameterType().equals(String.class)){
// 如果是String类需要特殊处理
ObjectMapper objectMapper = new ObjectMapper();
try {
// 设置响应数据格式为json
response.getHeaders().add("content-type","application/json;charset=UTF-8");
return objectMapper.writeValueAsString(Result.success(body));
} catch (JsonProcessingException e) {
throw new RuntimeException(e);
}
}
return Result.success(body);
}
}
项目打包
- 找到maven
- 先点clean清理,再点package打包
在target找到jar包,准备上传到云服务器
项目部署
xftp 上传文件 + xshell
通过xftp上传到云服务器
xshell执行jar
切换到当前jar目录下
# 启动
java -jar daily-weather-1.0.0.jar >/dev/null 2&1 &
# 启动成功会出现log目录,cd到log目录下可查看项目运行日志,有无报错
# 查看项目是否在运行
ps -ef | grep daily-weather-1.0.0.jar
# 可看到线程的pid
kill -9 pid号,可以杀死当前运行的项目
通过swagger访问
正常启动成功后,使用公网ip:端口/doc.html可以访问swagger页面
