Question

我使用 JERSEY框架在我目前的应用程序中开发了一些 REST服务。在此应用程序中，我将 RequestXML 发布到JERSEY并将 JSON 响应作为输出。

的web.xml

<servlet-name>VVCServices</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
      <param-name>com.sun.jersey.config.property.packages</param-name>
      <param-value>com.vzw.vvc.resources</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>VVCServices</servlet-name>
    <url-pattern>/customer/*</url-pattern>
  </servlet-mapping>

CustomerLookUp.java

@Path("/getCustInfo")
public class CustomerLookUp {

    private static Logger logger = Logger.getLogger(CustomerLookUp.class);

    @POST
    @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })

    public Response getCustomerInfo(VVC  vvc) throws Exception {

        logger.info("getCustomerInfo - ENTRY");

        String format="XML";
        Response response = null;
        com.vzw.vvc.customer.VVC.Response response1=new com.vzw.vvc.customer.VVC.Response();
        VVC.Response.CustomerInfo cusInfo =  new VVC.Response.CustomerInfo();    

          cusInfo.setEnrolled(true);
          cusInfo.setEnrolledDate(Utils.getXMLGregorianCalendarNow());
          cusInfo.setAccountNumber("23454");
          cusInfo.setDeviceId(new Long("56566"));
          cusInfo.setPlanId(new Long("4574963"));
          cusInfo.setBalancePastDue(true);
          response1.setCustomerInfo(cusInfo);
          vvc.setResponse(response1);

        ByteArrayOutputStream xml = new ByteArrayOutputStream();
        JAXBContext jaxbContext = JAXBContext.newInstance(VVC.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

        //output pretty printed
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        jaxbMarshaller.marshal(vvc,xml);
        response = Utils.getResponse(xml,format);
        logger.info("getCustomerInfo - Exit");
        return response;
    }
}

Utils.java

public class Utils {

    static Logger logger = Logger.getLogger(Utils.class);

    public static Response getResponse(ByteArrayOutputStream xmlResponse, String format) {

        Response response = null;
        JSONObject jsonObject;          

        logger.info(" in utils.java -- Entry");
        try {
            jsonObject = XML.toJSONObject(xmlResponse.toString());

            if (format.equalsIgnoreCase("JSON")) {
                response = Response.ok(jsonObject.toString(),
                        MediaType.APPLICATION_JSON).build();
            } else {
                response = Response.ok(xmlResponse.toString(),
                        MediaType.APPLICATION_XML).build();
            }

        } catch (Exception e) {
             e.printStackTrace();
        }
        return response;
}

    public static  XMLGregorianCalendar getXMLGregorianCalendarNow() 
            throws DatatypeConfigurationException
    {
        logger.info("IN getXMLGregorianCalendar()- Entry");
        GregorianCalendar gregorianCalendar = new GregorianCalendar();
        DatatypeFactory datatypeFactory = DatatypeFactory.newInstance();
        XMLGregorianCalendar now = 
            datatypeFactory.newXMLGregorianCalendar(gregorianCalendar);
        logger.info("XMLGregorianCalendar:"+now) ;
        return now;
    }
}

customerInfoPost.jsp 用于发布RequestXML和MIME类型..etc抛出JQUERY属性。

<input type="button" value="CustomerLookUpService" onClick="btnClick()"></input></br>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
var btnClick = function () {

            var reqXml = '<VVC><ServiceHeader><ServiceName>CustomerLookup</ServiceName><Operation>testing</Operation><ClientId>11333</ClientId><UserInfo><UserId>9933</UserId><UserClass>sampletestingclass</UserClass></UserInfo></ServiceHeader><Request><SearchCondition><CustomerId>2147483647</CustomerId></SearchCondition></Request></VVC>';

            var url = 'http://localhost:8080/VerizonVirtualCareServices/customer/getCustInfo';

            $.ajax({
                type:"POST",
                url: url,
                contentType: 'application/xml',
                cache: false,
                data: reqXml,
                dataType: "xml",

                success: function (data, textStatus, jqXHR) { 

                    onCompleted(data) 
                    },

                error: function (jqXHR, textStatus, errorThrown) {

                    onCompleted(textStatus); 
                    }
            });
        }

点击上述服务，这是JSON：

{"VVC":{"ServiceHeader":{"Operation":"testing","ServiceName":"manusample","UserInfo":{"UserClass":"sampletestingclass","UserId":"9933"},"ClientId":"11333"},"Response":{"CustomerInfo":{"DeviceId":"56566","BalancePastDue":"true","PlanId":"4574963","Enrolled":"true","AccountNumber":"23454","EnrolledDate":"2014-03-20T19:06:28.739+05:30"}},"Request":{"SearchCondition":{"CustomerId":"2147483647"}}}}

当时，为了 POC（概念验证），我应该将硬编码数据放在数据库上（oracle）并获得实际数据。

现在我想知道如何在Jersey Rest服务中使用 Spring jdbc 进行DataBase插件。

我希望对这篇文章作出回应，任何人都可以随意分享。

你可以一起使用Spring和Jersey。然后您的资源类（在您的情况下为CustomerLookup）可以初始化为具有范围“prototype”的bean，您可以正常注入JdbcTemplate。怎么做取决于你的泽西岛版本。我在Jersey 1.8上，我就是这样做的。

根据您的示例，在web.xml中更改servlet：

<servlet>
  <servlet-name>VVCServices</servlet-name>
  <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>com.vzw.vvc.resources</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>

如果您正在使用Spring注释，请将您的注释添加到类声明中：

@Component
@Scope("prototype")
@Path("/getCustInfo")
public class CustomerLookUp {
    private static Logger logger = Logger.getLogger(CustomerLookUp.class);

    @Autowired
    private JdbcTemplate jdbcTemplate

    @POST
    @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public Response getCustomerInfo(VVC  vvc) throws Exception {
        ... rest of your code ...
    }
}

当然，有很多方法可以初始化Spring bean，所以我不知道这是否适合你当前的方法，但这就是我在我的应用程序中所做的并且它运行良好。

如果您使用的是Jersey 2.x，可以在此处找到一个示例：https://github.com/jersey/jersey/tree/2.7/examples/helloworld-spring-webapp

如何使用Annotations将spring JDBCTemplate注入Jersey资源类（使用XML并生成JSON）？
