我是在春天新的。我正在嘗試構建我的第一個Web服務，並且我想連接到數據庫，獲取數據並將其作爲JSON返回。如何從STS（彈簧工具套件）連接到數據庫（oracle）
我使用彈簧的例子https://spring.io/guides/gs/rest-service，我改變了一下，所以我可以得到一個戰爭文件。
戰爭文件將部署的我的服務器是Wildfly 8.2.0。
我想連接到oracle 11g數據庫並運行SQL查詢。你可以幫我嗎？
我的代碼張貼如下。
Application.java：
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Greeting.java：
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
GreetingController.java：
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping(value="/greeting",method=RequestMethod.GET)
public List<Greeting> greeting(@RequestParam(value="name", defaultValue="World") String name,
@RequestParam(value="content", defaultValue="World") String content,HttpServletResponse response) {
List<Greeting> list_greet = new ArrayList<Greeting>();
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, content)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
//to have webservice work,beacause cors cut it out.
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
return list_greet;
}
}
