1、修改启动类

修改前：

package com.rsi.rc.ae;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cache.annotation.EnableCaching;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.openfeign.EnableFeignClients;import org.springframework.context.annotation.ComponentScan;import org.springframework.scheduling.annotation.EnableAsync;import org.springframework.scheduling.annotation.EnableScheduling;import springfox.documentation.swagger2.annotations.EnableSwagger2;@SpringBootApplication@EnableSwagger2@EnableDiscoveryClient@EnableCaching // 启用数据缓存@ComponentScan(value = "com.rsi.rc")@EnableFeignClients("com.rsi.rc")@EnableAsync@EnableSchedulingpublic class App {    public static void main(String[] args) throws InterruptedException {        SpringApplication.run(App.class, args);    }}

修改后：

package com.rsi.rc.ae;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;import org.springframework.cache.annotation.EnableCaching;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.openfeign.EnableFeignClients;import org.springframework.context.annotation.ComponentScan;import org.springframework.scheduling.annotation.EnableAsync;import org.springframework.scheduling.annotation.EnableScheduling;import springfox.documentation.swagger2.annotations.EnableSwagger2;@SpringBootApplication@EnableSwagger2@EnableDiscoveryClient@EnableCaching // 启用数据缓存@ComponentScan(value = "com.rsi.rc")@EnableFeignClients("com.rsi.rc")@EnableAsync@EnableSchedulingpublic class App extends SpringBootServletInitializer {    public static void main(String[] args) throws InterruptedException {        SpringApplication.run(App.class, args);    }    @Override    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {        return builder.sources(App.class);    }}

2、修改pom文件

     
      war
     

           
                 
      
       org.springframework.boot
                  
      
       spring-boot-starter-web
                  
                      
                           
        
         org.springframework.boot
                            
        
         spring-boot-starter-tomcat
                        
                   
          
     

           
               
      
       org.springframework.boot
                
      
       spring-boot-starter-tomcat
                
      
       provided
            
     

3、注意的地方：

1、application.xml 配置文件

　　配置的

　　　　　server.port

　　　　　server.servlet.context-path

　　将会失效 因为这些是配置内部tomcat的

2、还有tomcat访问是路径是带项目名的，这个和jar的方式是不一样的
