(一)IDEA中创建maven web项目
创建好项目后设置项目的编译路径:
(二)引入spring-boot项目所需的jar包:
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.2.RELEASE</version> <relativePath/> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <spring-boot.version>1.5.2.RELEASE</spring-boot.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot</artifactId> <version>${spring-boot.version}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <version>${spring-boot.version}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web --> <!-- spring-web, spring-webmvc Spring WebMvc框架 --> <!-- tomcat-embed-* 内嵌Tomcat容器 --> <!-- jackson 处理json数据 --> <!-- spring-* Spring框架 --> <!-- spring-boot-autoconfigure Spring Boot提供的自动配置功能 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>${spring-boot.version}</version> <!--<exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions>--> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <version>${spring-boot.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <version>${spring-boot.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> <version>${spring-boot.version}</version> </dependency> </dependencies> <build> <finalName>springBoot</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>
(三)配置文件、启动类:
项目路径如下:
application.yml配置文件中内容为:
#server
server:
# 项目contextPath,一般在正式发布版本中,我们不配置
context-path: /boot
# 该服务绑定IP地址,启动服务器时如本机不是该IP地址则抛出异常启动失败,只有特殊需求的情况下才配置
#address: 192.168.0.101
# 错误页,指定发生错误时,跳转的URL。请查看BasicErrorController源码便知
error:
path: /error
# 服务端口
port: 8080
# session最大超时时间(分钟),默认为30
session:
timeout: 60
tomcat:
# tomcat的URI编码
uri-encoding: utf-8
# tomcat最大线程数,默认为200
max-threads: 1000
# 存放Tomcat的日志、Dump等文件的临时文件夹,默认为系统的tmp文件夹(如:C:UsersShanhyAppDataLocalTemp)
basedir: G:/springboot-tomcat-tmp
# 打开Tomcat的Access日志,并可以设置日志格式的方法:
#server.tomcat.access-log-enabled=true
#server.tomcat.access-log-pattern=
Application.java启动类如下,spring会扫描该类所在目录下的java类:
package com.sun; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * @Configuration:标注此文件为一个配置项 * @EnableAutoConfiguration:使用自动配置 * @ComponentScan:可扫描的 * @SpringBootApplication 包含上面三个 * Application:启动管理器 * Created by sun on 2017-1-14. */ @SpringBootApplication public class Application implements CommandLineRunner { /* Servlet容器默认的Context路径是/ DispatherServlet匹配的路径(servlet-mapping中的url-patterns)是*//* @ComponentScan路径被默认设置为SampleController的同名package, 也就是该package下的所有@Controller,@Service, @Component, @Repository都会被实例化后并加入Spring Context中。*/ public static void main(String[] args) { SpringApplication springApplication = new SpringApplication(Application.class); springApplication.run(args); } // springboot运行后此方法首先被调用 // 实现CommandLineRunner抽象类中的run方法 @Override public void run(String... args) throws Exception { System.out.println("项目启动完成!"); } }
TestController类:
package com.sun.test.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import javax.servlet.http.HttpServletRequest; /** * 测试类 * Created by sun on 2017-1-14. */ @Controller @RequestMapping("/test") public class TestController { @RequestMapping("/") @ResponseBody String test(HttpServletRequest req){ return "Hello World!"; } }
启动Application,在页面上输入http://localhost:8080/boot/test/ 页面上打印出Hello World!
