Springboot前后端分离项目合并一起打war包

1.首先修改war包装方法

<packaging>war</packaging>

2.删除springboot内置tomcat方法1:使用exclusion标签排除web启动器自带的tomcat

注：使用此方法需要添加servlet依赖：

<dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>            <exclusions>                <exclusion>                    <groupId>org.springframework.boot</groupId>                    <artifactId>spring-boot-starter-tomcat</artifactId>                </exclusion>            </exclusions>  </dependency>  <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>            <scope>provided</scope> </dependency>

方法二:使用scope标签控制所依赖的使用范围，并将参数设置为provided

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

3.在build标签中设置包装文件名

<finalName>name</finalName>

4.修改启动类(启动类main方法打war包后不会执行)

@SpringBootApplication@MapperScan("com.ssq.mapper")@EnableSchedulingpublic class MyApplication extends SpringBootServletInitializer {     @Override    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {        return builder.sources(MyApplication.class);    }

5.在main方法中初始化一些业务之前，因为main方法不会在打war包后实施，所以建立一个新的配置类来实施业务初始化代码

@Componentpublic class BeginConfig implements ApplicationListener {@Overridepublic void onApplicationEvent(ContextRefreshedEvent event) {///在此编写项目启动后需要执行的初始代码}

6.将前端文件复制到resource目录下的static目录下7。在build标签下配置resource标签，确保将前端文件打到war包中

 <resource>      <directory>src/main/resources</directory>      <includes>         <include>**/*</include>       </includes>  </resource>

8.用maven插件包装，包装前最好是clean，然后部署在外部tomcat中即可访问
