Springboot项目发布war到tomcat

springboot项目有些日子没有开发了,新做一个min spring boot项目,复习下项目开发及发布流程。

1.新建项目:

 2.新建一个业务controller

controller名称及方法,名称随意,项目结构如下:

 testcontroller代码文件的内容如下:

package com.*****.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/test")
public class testController {
    @RequestMapping("/abc")
    public String abc()
    {
        return "ok.";
    }
}

3.修改启动配置

然后在项目的启动文件APP.java中修改启动配置如下:

package com.*****;

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;

/**
 * Hello world!
 *
 */
@SpringBootApplication
public class App extends SpringBootServletInitializer
{
    public static void main( String[] args )
    {
        //System.out.println( "Hello World!" );
        SpringApplication.run(App.class, args);
    }
    @Override  //这个表示使用外部的tomcat容器
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意这里要指向原先用main方法执行的启动类
        return builder.sources(App.class);
    }
}

其中继承SpringBootServletInitializer及重载configure是为了打包war时使用。

4.修改Pom文件:

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.*****</groupId>
  <artifactId>minispring</artifactId>
  <version>1.0-SNAPSHOT</version>

  <name>minispring</name>
  <!-- FIXME change it to the project's website -->
  <url>http://www.example.com</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
  </properties>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.6.RELEASE</version>
  </parent>
  <packaging>war</packaging>
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.apache.tomcat.embed</groupId>
      <artifactId>tomcat-embed-jasper</artifactId>
      <scope>provided</scope>
    </dependency>
    <!--打包不参与,也就是打包去掉tomcat-->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
      <scope>provided</scope>
    </dependency>
  </dependencies>
  <build>
      <plugins>
        <plugin>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-maven-plugin</artifactId>
          <configuration>
            <fork>true</fork>
            <jvmArguments>Dfile.encoding=UTF-8</jvmArguments>
            <!--配置入口类的标签名-->
            <mainClass>com.*****.App</mainClass>
          </configuration>
        </plugin>
      </plugins>
  </build>
</project>

其中,一般情况下,如果打包成jar包,则只需要引用spring-boot-maven-plugin即可,由于要打包为war包,则需要另外增加配置:tomcat-embed-jasper、spring-boot-starter-tomcat

5.在maven中进行打包

 打包完成后,将war包拷贝到tomcat的webapps目录下面(重命名为mi.war),运行tomcat即可自动解压war(tomcat默认自动解压war包,如果没有也可以手动配置)。

6.测试:

http://localhost:8080/mi/test/abc
