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。
