### SpringBoot打war包 ###

**1.配置pom.xml**

<packaging>war</packaging>
    
    
     
        <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>
          <version>3.1.0</version>
          <scope>provided</scope>
        </dependency>
    
    
        
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-tomcat</artifactId>
          
          <scope>provided</scope>
        </dependency>
    
    
    <build>
        <plugins>
          <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
          </plugin>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
              <source>1.8</source>
              <target>1.8</target>
            </configuration>
          </plugin>
          
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.18.1</version>
                    <configuration>
                        <skipTests>true</skipTests>
                    </configuration>
                </plugin>
        </plugins>
        <finalName>XXXXXX</finalName>
      </build>

**2.修改启动类Application**

import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    //继承SpringBootServletInitializer ，重写方法
    
    @SpringBootApplication
    public class StaticApplication extends SpringBootServletInitializer {
        
        public static void main(String[] args){
        
            SpringApplication.run(StaticApplication.class,args);
        }
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        
            return application.sources(StaticApplication.class);
        }
        }

**3.使用maven打包**  
1.clean 清除  
2.package 打包  
如何报错查看自己项目maven配置是否正常！！！

**4.注意事项**  
web.xml的内容

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
    </web-app>

启动后默认会打开index.jsp页面
