Spring Boot将项目打包成war包
1 修改项目打包类型
在pom.xml里,项目打包类型将jar设置成war:
<packaging>war</packaging>
2 移除内置tomcat容器
在pom.xml里设置:
<dependencies> <!--web启动器依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!--移除默认启动容器--> <exclusions> <exclusion> <artifactId>spring-boot-starter-tomcat</artifactId> <groupId>org.springframework.boot</groupId> </exclusion> </exclusions> </dependency>
3 添加servlet-api依赖
若项目的某些工具类会用到该依赖,如果缺失,会报错:
/tool/WebUtil.java:[6,26] 程序包javax.servlet.http不存在
需要在pom.xml里添加如下依赖:
<dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency>
或者下面依赖(任选其一):
<dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>8.0.36</version> <scope>provided</scope> </dependency>
4 修改项目启动类
Spring Boot入口类必须实现SpringBootServletInitializer接口的configure方法才能让外部容器运行Spring Boot项目。
原入口类MainApplication.java内容如下:
package com.maxbill; import com.maxbill.core.desktop.DesktopApp; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.context.ConfigurableApplicationContext; @SpringBootApplication @MapperScan("com.maxbill.base.dao") public class MainApplication extends DesktopApp { public static ConfigurableApplicationContext context; public static void main(String[] args) { //启动后台服务 context = SpringApplication.run(MainApplication.class, args); //启动桌面服务 launch(args); } }
修改后内容如下:
package com.maxbill; import com.maxbill.core.desktop.DesktopApp; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.context.ConfigurableApplicationContext; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.boot.builder.SpringApplicationBuilder; @SpringBootApplication @MapperScan("com.maxbill.base.dao") public class MainApplication extends SpringBootServletInitializer{ @Override //修改启动类,继承 SpringBootServletInitializer并重写 configure方法 protected SpringApplicationBuilder configure(SpringApplicationBuilder builder){ //注意这里要指向原先用main方法执行的Application启动类 return builder.sources(MainApplication.class); } public static ConfigurableApplicationContext context; public static void main(String[] args) { //启动后台服务 context = SpringApplication.run(MainApplication.class, args); //启动桌面服务 launch(args); } }
5 打包部署项目
maven执行命令跳过测试打包:
mvn clean package -DskipTests
build信息如下:
[INFO] Building war: D:\Workspace\MaxBill-RedisPlus-master\RedisPlus\target\RedisPlus-0.0.1-SNAPSHOT.war
[INFO]
[INFO] --- spring-boot-maven-plugin:2.0.4.RELEASE:repackage (default) @ RedisPlus ---
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
build成功后,在项目target目录下把war包部署到tomcat的webapps目录下,例如:
D:\Program Files\Apache Software Foundation\Tomcat 8.0\webapps
启动tomcat服务,在浏览器访问:
http://localhost:[端口号]/[打包项目名]/
