# springboot+jsp项目打包成jar/war包404解决方法 #

**描述**：springboot项目，前端使用jsp，现在需要将写有jsp页面的服务部署到服务器上，打包出现问题，导致部署不上去

**环境参数**：  
开发环境：inteliJ IDEA 2018  
JDK:Java 1.8

--------------------

**过程**：

## 打包成war包 ##

我项目里的pom.xml开始配置为war包，打包成war部署需要  
1.如果配置为jar要改成war

2.在pom.xml中添加一个dependency依赖（tomcat是外部提供的）

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>

3.创建web.xml有两种方式，一种是自己创建文件夹和文件，另一种创建文件夹，IDEA创建文件

4.在启动类添加（也可以创建一个Initializer类），继承自SpringBootServletInitializer，并重写configure方法，为了打包springboot项目用的。

3.打包方式可以用命令  
$ mvn clean package  
或者使用idea的插件打包，然后target目录下会出现war包

使用war包放到tomcat的webapp下，启动时会解压

## 项目启动 ##

我项目最开始放jsp的web-site服务的启动类是启动不了的，找到另一种启动方法使用springboot的插件来启动是可以的，就一直使用插件启动，插件启动是：

启动类无法使用，就无法打包成jar包启动（jar包启动默认是先去访问启动类）

--------------------

## 使用war包报错 ##

但是当我打包成war包就一直报错：

## war包的坑 ##

1.排除spring boot中内嵌的tomcat依赖包：

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>

2.打开Tomcat安装后目录，进入conf文件夹，找到配置文件server.xml，将

注释掉。（我使用没能解决问题）

3.查看是否是依赖包有相同的冲突了。

4.添加redis的配置，请检查Redis是否已经启动，或由于防火墙之类的原因无法访问。

5.查看注解是否有问题。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1B1ZGRpbmdaaGFu_size_16_color_FFFFFF_t_70 2]  
两个注解@EnableFeignClients、@EnableDiscoveryClient，启动类少其中任意一个就连接不上webclient（需要调用的另一个服务）

6.查看IDEA里的web.xml生成路径是否有问题。

--------------------

查找打包成war包需要的配置文件和别人的配置，对比了一天无果，仍然报错，决定使用jar包。

## 打包成jar包 ##

如果使用jar包就得先把我的启动类修好，所以就先来修复我的启动类了。

打包成jar包需要注意的是:

1.修改pom.xml里的为jar。

2.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。

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.weixin.SmallsystemApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

3.一种在程序的入口时main函数所在的类，使用==@SpringBootApplication==注解。

另一种和war包一样，在启动类添加（也可以创建一个Initializer类），继承自SpringBootServletInitializer，并重写configure方法。

4.在运行面板那有个运行配置，点开，点项目设置working directory工作路径，$MODEULE\_DIR（下拉框可选），不知道原理但是配置了我的启动类就可以访问jsp了 。

打包成jar包未解决之前报错：

5.打包成jar，还是用IDEA工具，先clean再install然后target目录下会出现jar包。
