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:
1
|
<packaging>war</packaging>
|
2 移除内置tomcat容器
在pom.xml里设置:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
<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:
1
2
3
4
5
6
|
<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):
1
2
3
4
5
6
|
<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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
|
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24

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]/
总结
