spring，hibernate，MVC，如何检测映射有什么问题

时间：2016-04-15 20:18:07

标签： hibernate spring-mvc tomcat netbeans-8

我使用Netbeans 8.1从和下载解决方案和托盘2教程 P1。 Spring Hibernate Integration Example Tutorial (Spring 4 + Hibernate 3 and Hibernate 4) P2。 Spring MVC Hibernate MySQL Integration CRUD Example Tutorial 原始项目是与eclipse。我用过Netbeans。

P1工作正常。

当我跑P2时，我得到了：

HTTP状态404 - 和 没有找到带URI的HTTP请求的映射，如下所示。

System.exit

以下是部署的内容：

我的问题是，只要我保留原始文件，如何检测映射有什么问题？

感谢您的帮助。

当我在netbeas中运行应用程序时，它是在服务器上部署和启动web的人。我不是那个写url地址的人。

Netbeans让我通过右键单击菜单（server - tomcat - SpringMVCHibernate）来启动，停止，在浏览器中打开。

我尝试了其他一些网址，但没有成功。

所有来源都可以在P2的地址上看到。

更新

我更改了log4j.xml级别，以下是我在浏览器中打开的内容：

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;

@Controller
public class PersonController {

    private PersonService personService;

    @Autowired(required=true)
    @Qualifier(value="personService")
    public void setPersonService(PersonService ps){
        this.personService = ps;
    }

    @RequestMapping(value = "/persons", method = RequestMethod.GET)
    public String listPersons(Model model) {
        model.addAttribute("person", new Person());
        model.addAttribute("listPersons", this.personService.listPersons());
        return "person";
    }

    //For add and update person both
    @RequestMapping(value= "/person/add", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("person") Person p){

        if(p.getId() == 0){
            //new person, add it
            this.personService.addPerson(p);
        }else{
            //existing person, call update
            this.personService.updatePerson(p);
        }

        return "redirect:/persons";

    }

    @RequestMapping("/remove/{id}")
    public String removePerson(@PathVariable("id") int id){

        this.personService.removePerson(id);
        return "redirect:/persons";
    }

    @RequestMapping("/edit/{id}")
    public String editPerson(@PathVariable("id") int id, Model model){
        model.addAttribute("person", this.personService.getPersonById(id));
        model.addAttribute("listPersons", this.personService.listPersons());
        return "person";
    }

}

我认为一些相关问题是：
TRACE: org.springframework.web.servlet.DispatcherServlet - Bound request context to thread: uri: /SpringMVCHibernate/ method: GET QueryString: null Parameters: Headers: Name: host Value: localhost:8080 Name: user-agent Value: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Name: accept Value: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Name: accept-language Value: en-US,en;q=0.5 Name: accept-encoding Value: gzip, deflate Name: dnt Value: 1 Name: connection Value: keep-alive DEBUG: org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'appServlet' processing GET request for [/SpringMVCHibernate/] TRACE: org.springframework.web.servlet.DispatcherServlet - Testing handler map [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping@43edc0b9] in DispatcherServlet with name 'appServlet' DEBUG: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Looking up handler method for path / DEBUG: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Did not find handler method for [/] TRACE: org.springframework.web.servlet.DispatcherServlet - Testing handler map [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping@170563eb] in DispatcherServlet with name 'appServlet' TRACE: org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping - No handler mapping found for [/] TRACE: org.springframework.web.servlet.DispatcherServlet - Testing handler map [org.springframework.web.servlet.handler.SimpleUrlHandlerMapping@5256ecaa] in DispatcherServlet with name 'appServlet' TRACE: org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - No handler mapping found for [/] WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/SpringMVCHibernate/] in DispatcherServlet with name 'appServlet' TRACE: org.springframework.web.servlet.DispatcherServlet - Cleared thread-bound request context: uri: /SpringMVCHibernate/ method: GET QueryString: null Parameters: Headers: Name: host Value: localhost:8080 Name: user-agent Value: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Name: accept Value: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Name: accept-language Value: en-US,en;q=0.5 Name: accept-encoding Value: gzip, deflate Name: dnt Value: 1 Name: connection Value: keep-alive DEBUG: org.springframework.web.servlet.DispatcherServlet - Successfully completed request TRACE: org.springframework.web.context.support.XmlWebApplicationContext - Publishing event in WebApplicationContext for namespace 'appServlet-servlet': ServletRequestHandledEvent: url=[/SpringMVCHibernate/]; client=[127.0.0.1]; method=[GET]; servlet=[appServlet]; session=[null]; user=[null]; time=[2ms]; status=[OK] TRACE: org.springframework.web.context.support.XmlWebApplicationContext - Publishing event in Root WebApplicationContext: ServletRequestHandledEvent: url=[/SpringMVCHibernate/]; client=[127.0.0.1]; method=[GET]; servlet=[appServlet]; session=[null]; user=[null]; time=[2ms]; status=[OK] ，servlet-context.xml和root-context.xml的用途是什么？ 为什么DispatcherServlet会创建另一个应用程序上下文？ 上下文初始化失败或加载属性
根上下文和调度程序servlet上下文到底是如何进入Spring MVC Web应用程序的？

尝试在Eclipse上运行示例并获得相同的结果：

web.xml

仍然不知道如何修复以及如何检测应用程序的错误。 谢谢你的帮助。

您的项目中有一个Controller，它会处理一组网址。 它在您项目的日志级别INFO上提及。

INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/persons],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.journaldev.spring.PersonController.listPersons(org.springframework.ui.Model)
INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/person/add],methods=[POST],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.journaldev.spring.PersonController.addPerson(com.journaldev.spring.model.Person)
INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/remove/{id}],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.journaldev.spring.PersonController.removePerson(int)
INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/edit/{id}],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.journaldev.spring.PersonController.editPerson(int,org.springframework.ui.Model)
INFO : org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - Mapped URL path [/resources/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#0'

是：

/persons 
/person/add
/remove/{id}
/edit/{id}

您的警告是因为您使用以下表单致电Url：

http://localhost:xxxx/SpringMVCHibernate/

未映射到您的servlet上。

我再次托起Netbeans的例子，让它发挥作用。我希望在网址上看到一个页面，这是错误的：http://localhost:8080/SpringMVCHibernate如果我将网址更改为：http://localhost:8080/SpringMVCHibernate/persons我收到错误：

HTTP Status 500 – Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection
…
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class ‘com.mysql.jdbc.Driver’

我添加了mysql-connector，我看到了正确的页面; 谢谢你的评论 M. Toma
