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
