我目前正在研究运行在Apache Tomcat 7上的Java Web应用程序。由于我想将某些信息记录到数据库中,因此我使用以下配置文件信息来启动我的记录仪:在java web服务上记录事件
log4j.rootLogger = DEBUG, DB
log4j.appender.DB=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.DB.URL=jdbc:mysql://localhost:3306/cap_recommender_log
log4j.appender.DB.driver=com.mysql.jdbc.Driver
log4j.appender.DB.user=log_user
log4j.appender.DB.password=some_password
log4j.appender.DB.sql=INSERT INTO notify_service_log(date, logger, level, message) VALUES('%d{YYYY-MM-dd}','%C','%p','%m')
log4j.appender.DB.layout=org.apache.log4j.PatternLayout
此外,notify_service_log表如下:
CREATE TABLE `notify_service_log` (
`date` date NOT NULL,
`logger` varchar(256) NOT NULL,
`level` varchar(10) NOT NULL,
`message` text NOT NULL,
KEY `index_level` (`level`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=latin1
最后,Web服务代码如下:
package com.imis.cap.service.notify;
import com.imis.cap.module.etl.EtlModuleClient;
import gr.aia.cap.eventbroker.v1.ArrayOfServiceMessage;
import gr.aia.cap.eventbroker.v1.BooleanResponse;
import gr.aia.cap.eventbroker.v1.ServiceMessage;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.jws.WebService;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
@WebService(serviceName = "NotifyService", portName = "HttpBinding_NotifyService", endpointInterface = "gr.aia.cap.eventbroker.v1.NotifyService", targetNamespace = "http://www.aia.gr/cap/eventbroker/v1/", wsdlLocation = "WEB-INF/wsdl/NotifyService/NotifyService.wsdl")
public class NotifyService {
private String username;
private String password;
private String log_properties_file;
private DataSource registration_db;
private static org.apache.log4j.Logger notifyServiceLogger =
Logger.getLogger(NotifyService.class);
public NotifyService() {
Context context;
try {
context = (Context) new InitialContext().lookup("java:comp/env");
this.username = (String) context.lookup("CAP_RECOMMENDER_UNAME");
this.password = (String) context.lookup("CAP_RECOMMENDER_PASS");
this.registration_db = (DataSource) context.lookup("jdbc/cap_registration_db");
this.log_properties_file = (String) context.lookup("NOTIFY_SERVICE_LOG_PROPERTIES_FILE");
}catch(NamingException e) {
System.err.println(e.getMessage());
notifyServiceLogger.error("NotifyService: NamingException occured during construction. Message: " +
e.getMessage());
}
PropertyConfigurator.configure(this.log_properties_file);
notifyServiceLogger.info("NotifyService: Object constructor completed successfully.");
}
public gr.aia.cap.eventbroker.v1.BooleanResponse notify(gr.aia.cap.eventbroker.v1.NotifyRequest request) throws ParseException {
ArrayOfServiceMessage arrayOfServiceMsg = new ArrayOfServiceMessage();
ServiceMessage msg = new ServiceMessage();
BooleanResponse response = new BooleanResponse();
EventTypeReader eventType = new EventTypeReader(request);
String regCode = request.getRegistrationCode();
String dbRegCode = "";
**notifyServiceLogger.info("NotifyService.notify(): Called with reg-code: " + request.getRegistrationCode() + ".");**
/**Some more code**/
return new BooleanResponse(); //Sample response
}
}
执行的通知程序的调用客户端代码如下:
package notifyclient;
import gr.aia.cap.eventbroker.v1.ArrayOfAttribute;
import gr.aia.cap.eventbroker.v1.BooleanResponse;
import gr.aia.cap.eventbroker.v1.EventType;
import gr.aia.cap.eventbroker.v1.NotifyRequest;
public class NotifyClient {
public static void main(String[] args) {
NotifyRequest request = new NotifyRequest();
request.setRegistrationCode("blasdadasd");
request.setAttributes(new ArrayOfAttribute());
request.setEventType(EventType.USER);
BooleanResponse response = notify(request);
System.out.println("Output: " + response.getErrors().getServiceMessage().toString());
}
public static gr.aia.cap.eventbroker.v1.BooleanResponse notify(gr.aia.cap.eventbroker.v1.NotifyRequest request) {
gr.aia.cap.eventbroker.v1.NotifyService_Service service = new gr.aia.cap.eventbroker.v1.NotifyService_Service();
gr.aia.cap.eventbroker.v1.NotifyService port = service.getHttpBindingNotifyService();
return port.notify(request);
}
}
我在这一点上,通知您所需要执行的Web服务调用所需的类是自动生成的由Netbeans 7.2提供。
问题在于构造函数的消息已登录到数据库中,但通知函数中的信息消息从不记录。这是为什么发生?有任何想法吗?
被通知过吗?还是这个类只是构造? – Lipongo
是的。为了执行对Web服务的请求,我开发了一个测试客户端。构造函数日志消息被插入到数据库中,但通知调用不是。 –
你可以发布客户端代码,这样我们就可以看到它被调用,如果问题出现在客户端而不是此代码中? – Lipongo
