Spring Boot 打包war

1.修改打包格式war

<packaging>war</packaging>

2.修改代码入口

@SpringBootApplication
@MapperScan("com.example.demo.dao")
public class DemoApplication extends SpringBootServletInitializer {

   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

      return application.sources(DemoApplication.class);
   }

   public static void main(String[] args) {
      SpringApplication.run(DemoApplication.class, args);
   }
}

3.添加引用

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

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-war-plugin</artifactId>
   <configuration>
      <failOnMissingWebXml>false</failOnMissingWebXml>
   </configuration>
</plugin>

<configuration>
   <fork>true</fork>
   <mainClass>com.example.demo.DemoApplication</mainClass>
</configuration>
<executions>
   <execution>
      <goals>
         <goal>repackage</goal>
      </goals>
   </execution>
</executions>

<resources>
   <!-- 打包时将jsp文件拷贝到META-INF目录下-->
   <resource>
      <!-- 指定resources插件处理哪个目录下的资源文件 -->
      <directory>src/main/webapp</directory>
      <!--注意此次必须要放在此目录下才能被访问到-->
      <targetPath>META-INF/resources</targetPath>
      <includes>
         <include>**/**</include>
      </includes>
   </resource>
   <resource>
      <directory>src/main/resources</directory>
      <includes>
         <include>**/**</include>
      </includes>
      <filtering>false</filtering>
   </resource>
</resources>

4.javax/el/ELManager异常

从intellij安装目录下lib/rt/jasper2.1/el-api.jar拷贝到tomcat/lib/
