Spring Boot将项目打包成war包的操作方法
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
:[端口号]/[打包项目名]/
