Consuming a RESTful Web Service

创建项目步骤不做描述了直奔主题

1.修改pom.xml 文件

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.2.RELEASE</version>
</parent>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>
</dependencies>

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

<repositories>
<repository>
<id>spring-release</id>
<url>https://repo.spring.io/libs-release</url>
</repository>
</repositories>

<pluginRepositories>
<pluginRepository>
<id>spring-release</id>
<url>https://repo.spring.io/libs-release</url>
</pluginRepository>
</pluginRepositories>

2.添加实体类

@JsonIgnoreProperties(ignoreUnknown = true)
public class Greeting {

private String id;
private String content;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getContent() {
return content;
}

public void setContent(String content) {
this.content = content;
}

}

3.添加测试类

public class Application {

public static void main(String[] args) {
RestTemplate restTemplate = new RestTemplate();
Greeting page = restTemplate.getForObject("http://localhost:8080/greeting", Greeting.class);
System.out.println("id:" + page.getId());
System.out.println("content:" + page.getContent());
}

}

4.测试打印成功：

id:0
content:hello,world!

总结：将restful系统返回的内容转换成普通的java对象
