如何从 STS（spring 工具套件）连接到数据库（oracle）答案

【问题描述】：

我是春天的新人。我正在尝试构建我的第一个 Web 服务，我想连接到数据库、获取数据并将其作为 JSON 返回。

我使用 spring 示例 https://spring.io/guides/gs/rest-service 并稍作更改，这样我可以获得一个战争文件。

war 文件将部署的我的服务器是 Wildfly 8.2.0。

我想连接到 oracle 11g 数据库并运行 SQL 查询。你能帮帮我吗？

我的代码贴在下面。

My project format in eclipse

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);
}


}

问候.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;
}
}
