快速搭建一个restful风格的springboot项目

1.创建一个工程。



2.引入pom.xml依赖，如下

<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.xiaowu</groupId>
<artifactId>springBootDemo</artifactId>
<version>0.0.1-SNAPSHOT</version>

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>

<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>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>

3.这个时候项目会提示报错，如下:



4.根据提示，解决问题。



5.操作如下:







6.编写domain类

package com.xiaowu.domain;

public class Phone {
private String phoneName;
private String phoneNumber;

public String getPhoneName() {
return phoneName;
}

public void setPhoneName(String phoneName) {
this.phoneName = phoneName;
}

public String getPhoneNumber() {
return phoneNumber;
}

public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}

}

7.编写controller类

package com.xiaowu.controller;

import java.util.HashMap;
import java.util.Map;

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

@RestController
@RequestMapping(value="/phone")
public class PhoneController {

@RequestMapping
public String index(){
return "Hello World!";
}

@RequestMapping(value="/getmap")
public Map<String,String> getMap(){
Map<String,String> phoneMap = new HashMap<String,String>();
phoneMap.put("name", "apple phone");
phoneMap.put("money", "5000");
return phoneMap;
}
}

8.编写启动类

package com.xiaowu;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}

}

9.这个时候，直接启动的话，不好意思会报错，如下。



因为我们引入了

</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

，但是刚才的启动中没有在项目的配置文件中引入mysql数据库的相关信息，所以报错。

10.引入配置文件即可，当然我们的数据库中要真实的存在相关的表。



11.再次启动，OK.



12.使用Chrome接口测试工具测试效果。











至此，一个简单的基于SpringBoot的Restful WebService搭建完成。
