Restful接口实现实例

rest需要jar包：

web.xml加如下配置：

<context-param>
<param-name>org.restlet.application</param-name>
<param-value>vs.dascsl.restservice.app.RestJaxRsApplication</param-value>
</context-param>
<servlet>
<servlet-name>RestletServlet</servlet-name>
<servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RestletServlet</servlet-name>
<url-pattern>/restServices/*</url-pattern>
</servlet-mapping>

服务接口Rest资源加载App类：

public class ServiceInterfaceApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
        Set<Class<?>> rrcs = new HashSet<Class<?>>();
// rrcs.add(ServDataResource.class);// 这个application中绑定这三个reource。
// rrcs.add(ServMetaResource.class);// 用一个application管理多个resource
// rrcs.add(UserLoginResource.class);
        rrcs.add(ModelChangeResource.class);
return rrcs;
    }
}

Rest接口JAX风格App类：
加入了运行环境中，如果有多个Application可以在此绑定。

/***
 * Rest接口JAX风格App类.
 * @author gengjanlu
 * 
 *///创建运行环境。RESTlet 架构为了更好的支持 JAX-RS 规范，定了 JaxRsApplication 类来初始化基于 JAX-RS 的 Web Service 运行环境。
public class RestJaxRsApplication extends JaxRsApplication {
/**
 * 初始化.
 * @param context 上下文
 */
public RestJaxRsApplication(Context context) {
super(context);
this.add(new ServiceInterfaceApplication());
// this.add(new DomainAndDatasetMetaApp());
    }
}

测试类TestRestClient：

public class TestModelRestClient {
public static String url="http://127.0.0.1:8080/DASBASE/restServices/";
public static String testModel(){
        ClientResource client = new ClientResource(url+"modelChangeService/compCollectModelVersion");
        String body = "";
// 查询模型变更
try {
        Form form = new Form();
        form.add("jsonData","{\"localVersion\":\"V2.002\"}");
        body =  client.post(form.getWebRepresentation()).getText();
        } catch (Exception e) {
            e.printStackTrace();
        }
         System.out.println(body);  //
return body;
    }
public static void main(String[] args) {
        testModel();
    }
}

Resource类：

@Path("modelChangeService")
public class ModelChangeResource {
@POST
@Path("compCollectModelVersion")
public String compCollectModelVersion(Representation entity) {
        String result = "";
try {
        Form form = new Form(entity);
        String json = form.getFirstValue("jsonData");
        JSONObject to_json = JSONObject.fromObject(json);
        String to_string = (String) to_json.get("localVersion");
        result = ModelChangeServiceImpl.compCollectModelVersion(to_string);
        } catch (Exception e) {
            e.printStackTrace();
        }
return result;
    }
}

ServiceImpl类：

public static String compCollectModelVersion(String localVersion) throws Exception {
        localVersion = localVersion.substring(1);
String ver[] = localVersion.split("\\.");
String bigVer = ver[0];
String smallVer = ver[1];
String versionList = "";
        Map<String, String> dataMap = new LinkedHashMap<String,String>();
        Map<String, String>versionMap = versionData();
if(versionMap.get("VERSION_CODE").equals(bigVer) && versionMap.get("NEW_CHANGE_CODE").substring(1).equals(smallVer)){
            dataMap.put("isEqual", "true");
        }else {
String verSql = "SELECT c.change_code FROM mv_oobpm_version_change c where c.change_code between 'C"+smallVer+"' and '"+versionMap.get("NEW_CHANGE_CODE")+"'";
            List<Map<String, String>> dataList = DBService.getModelMgrInstance().queryForList(verSql);
for(Map<String,String> map:dataList){
                versionList+="V"+versionMap.get("VERSION_CODE")+"."+map.get("CHANGE_CODE").substring(1)+",";
            }
            dataMap.put("isEqual", "false");
            dataMap.put("lastVersion", "V"+versionMap.get("VERSION_CODE")+"."+versionMap.get("NEW_CHANGE_CODE").substring(1));
            dataMap.put("versionList", versionList.substring(0, versionList.length()-1));
        }
        return new Gson().toJson(dataMap);
    }
