使用Eclipse对SpringBoot项目如何进行打包部署

## **1，打包概要介绍:** ##

自己做了个小demo，突然想练一下如何打包发布，期间出现了两个错误，第一个是加载不到主类，第二个是加载不到jsp文件，一会会把这两个问题一一陈述,以及解决方法。

### **1.1，先检查pom文件** ###

因为springboot的项目打包的话他是根据pom.xml文件进行打包的，注意：（仔细观看我写的注释，加载不到jsp文件那你还要回头再看）

### 1.2，pom.xml中需要注意的地方 ###

注意pom.xml最下面的build这块一定要配置否则打jar的时候会说找不到主类（我标红的地方则是Springboot的启动类路径,咱们的路径肯定不一样修改一下哈）

### 1.3，启动类代码修改 ###

在启动类当中加上继承 SpringBootServletInitializer类并重写configure方法，这是为了打包springboot项目用的(不是单单实现就完事了，有些代码还需要修改一下，仔细点)

1 package com.example.demo;
     2 
     3 import org.springframework.boot.SpringApplication;
     4 import org.springframework.boot.autoconfigure.SpringBootApplication;
     5 import org.springframework.boot.builder.SpringApplicationBuilder;
     6 import org.springframework.boot.web.support.SpringBootServletInitializer;
     7 
     8 @SpringBootApplication
     9 public class SpringBootDay02Application extends SpringBootServletInitializer{
    10 
    11     public static void main(String[] args) {
    12         SpringApplication.run(SpringBootDay02Application.class, args);
    13     }
    14     //为springboot打包项目用的
    15     @Override
    16     protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    17         // TODO Auto-generated method stub
    18         return builder.sources(this.getClass());
    19     }
    20 }

### 1.4，application.properties文件检查 ###

**　　　　**代码大致不需要修改，就是检查各个应用连接之类的，假如在虚拟机上部署的话则需要进行一些修改，端口号啊，环境配置连接等等

1 server.port=8080
     2 server.servlet.context-path=/
     3 debug=false
     4 
     5 spring.datasource.url=jdbc:mysql://localhost:3306/stores-erp?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true
     6 spring.datasource.driver-class-name=com.mysql.jdbc.Driver
     7 spring.datasource.username=root
     8 spring.datasource.password=321
     9 
    10 spring.mvc.view.prefix=/WEB-INF/jsp/
    11 spring.mvc.view.suffix=.jsp
    12 
    13 mybatis.config-location=classpath:mybatis/mybatis-config.xml
    14 mybatis.mapper-locations=classpath:mybatis/mappers/*/*.xml
    15 mybatis.type-aliases-package=com.example.demo.pojo

## 2.1，第一步， ##

点击项目右键，Run As=》Maven Clean进行项目刷新

![1426493-20190712100116467-1685952923.png][]

### 2.2，第二步， ###

**　**　Run As=》Maven insert进行项目打包，假如成功的话则出现以下页面信息:

![1426493-20190712103011554-1054852529.png][]

### 2.3，第三步， ###

**　　**我们找到项目中的target文件就可以看到我们的jar包文件等等了。

**![1426493-20190712103304659-968626747.png][]**

### 2.4，第四步， ###

**　　**你可以选择直接把stores-erp-0.01-SNAPSHOT.jar拷贝出去，也可以直接去他目录下找它，我选择的是找到项目中的jar文件的所在地址，在导航栏输入cmd。

**![1426493-20190712103842139-385008060.png][]**

### 2.5，第五步， ###

启动jar包项目，注意:我之前做的时候这边出了个错误，就是加载不到主类等等，是个非常操蛋的错误就是因为少加了个 -  这个坑我提你们踩了- -.（这个执行方式windows和linux上都一样）

## 3，然后就可以进行访问了效果如下： ##
