第一步：创建一个普通的maven项目
第二步：配置springboot基础依赖配置（即配置pom和启动类）
POM配置
<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>spring-boot-example</groupId>
<artifactId>spring-boot-example</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>spring-boot-example</name>
<description>spring-boot-example</description> <!-- 继承父包 -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.19.RELEASE</version>
<relativePath></relativePath>
</parent> <dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies> <properties>
<java.version>1.8</java.version>
</properties> <build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
配置启动类
@RestController // @RestController 相当于 @Controller 加上 @ResponseBody
@EnableAutoConfiguration
public class HelloController { public static void main(String[] args) {
SpringApplication.run(HelloController.class, args);
} @RequestMapping("/example/hello")
public int hello(){
return 1;
} }
最后，启动springboot应用
方式一：eclipse中直接运行main方法
方式二：命令行执行 java -jar spring-boot-example.jar &
方式三：打包成war文件，放tomcat中运行
结果如下图所示：
发布的http服务测试：http://localhost:8080/example/hello，测试成功！，如下图所示
关于打包成war形式，放入tomcat中运行需要注意：
第一步：修改pom文件：新增黑色字体部分内容
<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>spring-boot-example</groupId>
<artifactId>spring-boot-example</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>spring-boot-example</name>
<description>spring-boot-example</description>
<packaging>war</packaging> <!-- 继承父包 -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.19.RELEASE</version>
<relativePath></relativePath>
</parent> <dependencies> <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency> <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency> <!-- 确保内置servlet container 不会干涉发布该war包的servlet container，方案是标记内置servlet container 的依赖为 provided -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
第二步：更改程序入口类 Application.java 使其继承SpringBootServletInitializer，并重写configure方法，（即加粗字体部分）
@RestController // @RestController 相当于 @Controller 加上 @ResponseBody
@SpringBootApplication
public class HelloController extends SpringBootServletInitializer{ @Override
public SpringApplicationBuilder configure(SpringApplicationBuilder application){
return application.sources(HelloController.class);
} public static void main(String[] args) {
SpringApplication.run(HelloController.class, args);
} @RequestMapping("/example/hello")
public int hello(){
return 1;
}
}
用 tomcat验证结果：
