spring boot配置tomcat部署

spring boot本身默认为jar包运行，可以改为war包，然后运行在tomcat里

具体修改的步骤如下：

1.在pom.xml文件里添加需要的依赖：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--以下是在tomcat运行比spring boot多引的包-->
<dependency>           <groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId>
</dependency>

以上两个依赖还需要引入下边一个spring boot的父依赖。

  <!-- Spring Boot 启动父依赖 -->
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.1.RELEASE</version>
</parent>

为了访问到jsp页面还需要加jstl依赖

<dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version>
</dependency>

为了部署到tomcat里，那packing 标签必须要改成war

<packaging>war</packaging>

2.最后修改启动类：

package microservice.springboot;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;/*** 即继承SpringBootServletInitializer类，并重写它的 configure方法即可*/
@SpringBootApplication
public class CreateModelApplication extends SpringBootServletInitializer{public static void main(String[] args){SpringApplication.run(CreateModelApplication.class,args);}@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(CreateModelApplication.class);}
}

注意了，这样配置，并不是说只能用tomcat来启动，也是可以直接main方法启动的，瞬间高大上了不是？

3.然后在项目的src/main/下创建一个新的文件夹webapp，我们放进两个jsp文件和js用来测试，配置到这里，就可以启动tomcat查看了，配置情况如下图：

4.启动tomcat，访问index.jsp

5.如果你还想让将来打包的结构规范一些，可以在pom.xml里加上如下配置：

<build><resources><resource><directory>${basedir}/src/main/resources</directory><includes><include>application.properties</include><include>dubbo-consumer.xml</include><include>logback-spring.xml</include></includes><filtering>true</filtering></resource><resource><directory>${basedir}/src/main/webapp</directory><!--这里是将webapp下的文件都打包复制到下边目录下 --><targetPath>META-INF/resources</targetPath><includes><include>**/**</include></includes></resource><resource><!--下边的这个resource，这个其实在这里没有用，可以删掉-->  <directory>${basedir}/src/main/resources</directory><includes><include>**/**</include></includes></resource></resources><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>1.5.1.RELEASE</version><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-surefire-plugin</artifactId><configuration><useSystemClassLoader>false</useSystemClassLoader></configuration></plugin></plugins>
</build>
