Spring boot starts the web, embedded tomcat, springtomcat

1. Configure the pom. xml file (as appropriate)

<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.nnk.maven.test</groupId><artifactId>test-sample</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><properties><java.version>1.7</java.version><start-class>com.nnk.maven.test.boot.Application</start-class></properties><!-- Inherit defaults from Spring Boot --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.0.1.RELEASE</version></parent><!-- Add typical dependencies for a web application --><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies><build><pluginManagement><plugins><plugin><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.7</source><target>1.7</target></configuration></plugin></plugins></pluginManagement></build><repositories><repository><id>spring-snapshots</id><url>http://repo.spring.io/snapshot</url><snapshots><enabled>true</enabled></snapshots></repository><repository><id>spring-milestones</id><url>http://repo.spring.io/milestone</url></repository></repositories><pluginRepositories><pluginRepository><id>spring-snapshots</id><url>http://repo.spring.io/snapshot</url></pluginRepository><pluginRepository><id>spring-milestones</id><url>http://repo.spring.io/milestone</url></pluginRepository></pluginRepositories></project>

2. entity class User

package com.nnk.maven.test.entity;/** *  */public class User {private Long id;private String name;public Long getId() {return id;}public void setId(Long id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic boolean equals(Object o) {if (this == o)return true;if (o == null || getClass() != o.getClass())return false;User user = (User) o;if (id != null ? !id.equals(user.id) : user.id != null)return false;return true;}@Overridepublic int hashCode() {return id != null ? id.hashCode() : 0;}}

3. Controller

package com.nnk.maven.test.controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import com.nnk.maven.test.entity.User;/** *  */@RestController@RequestMapping("/user")public class UserController {@RequestMapping("/{id}")public User view(@PathVariable("id") Long id) {User user = new User();user.setId(id);user.setName("zhang");return user;}}

4. spring-boot (tomcat startup)

package com.nnk.maven.test.boot;import java.util.HashSet;import java.util.Set;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;/** *  */@Configuration@ComponentScan("com.nnk")@EnableAutoConfiguration// @SpringBootApplicationpublic class Application {public static void main(String[] args) {SpringApplication app = new SpringApplication(Application.class);app.setWebEnvironment(true);app.setShowBanner(false);Set<Object> set = new HashSet<Object>();// set.add("classpath:applicationContext.xml");app.setSources(set);app.run(args);}}

Note: Most @ CompoentScan on the Internet does not have the following value. If no value is added, make sure that all programs are in the same package. Otherwise, 404 is displayed.

LZ also found this problem after several hours, so it was quite complete to avoid people making the same mistake again!
