简单的rest template,并且gradle打成可执行的jar包

@SpringBootApplication
public class MainApplication {
    public static void main(String[] args) {
        RestTemplate template = new RestTemplate();
        String url = "";
        ResponseEntity<String> res =
                template.exchange(url, HttpMethod.GET,
                        new RequestEntity<String>(null,null),String.class);
        System.out.println(res.getBody());
    }
}
get请求，返回string类型

gradle.build配置文件

buildscript {
    ext {
        springBootVersion = '2.0.4.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
//使用插件，将项目中引用jar包打进jar

jar {
    manifest {
        attributes 'Main-Class': 'test.MainApplication'
    }
    //into('lib') {
      //  from configurations.runtime
    //}
}
