我是 Spring MVC 框架的新手，在使用两个不同的控制器进行基本 URL 映射时遇到了一些问题。我正在使用@Controller 和@RequestMapping。

以下导致 /people 和 /accounts 的 404 错误。

这是我的 Spring MVC 3.1 设置：

索引.jsp

<!DOCTYPE html>
<html>
<head>
    <title>t-diggity</title>
</head>
<body>
    <h1>integration</h1>
    <a href="/people/">Contact List</a><br>
    <a href="/accounts/">Account List</a><br>
</body>
</html>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     version="2.5">

<display-name>t-diggity</display-name>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
            <param-name>contextAttribute</param-name>
            <param-value>org.springframework.web.servlet.FrameworkServlet.CONTEXT.spring</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

<servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/people/*</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/assets/*</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/accounts/*</url-pattern>
    </servlet-mapping>

</web-app>

控制器＃1：PersonController.java

@Controller
@RequestMapping("/people/")
public class PersonController {

    @Autowired
    private PersonService personService;

    @RequestMapping("/")
    public String listPeople(Map<String, Object> map) 
    {
        map.put("person", new Person());
        map.put("peopleList", personService.listPeople());
        return "people";
    }

    @RequestMapping(value = "/addPerson", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("person") Person person, BindingResult result
    {
        personService.addPerson(person);
        return "redirect:/people/";
    }

    @RequestMapping("/delete/{personId}")
    public String deletePerson(@PathVariable("personId") String personId) 
    {
        personService.removePerson(personId);
        return "redirect:/people/";
    }
}

控制器 #2：AccountController.java

@Controller
@RequestMapping("/accounts")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/")
    public String listAccounts(Map<String, Object> map) 
    {
        map.put("account", new Account());
        map.put("accountList", accountService.listAccounts());
        return "accounts";
    }

    @RequestMapping(value = "/addAccount", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("account") Account account, 
                            BindingResult result) 
    {
        accountService.addAccount(account);
        return "redirect:/accounts/";
    }

    @RequestMapping("/delete/{accountId}")
    public String deleteAccount(@PathVariable("accountId") String accountId) {
        accountService.removeAccount(accountId);
        return "redirect:/accounts/";
    }

}

我希望我的错误是一个小错误，我是 URL 映射的新手，所以它可能是小错误......我会很感激任何指导，在此先感谢。

更改index.jsp为：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<!DOCTYPE html>
<html>
<head>
    <title>t-diggity</title>
</head>
<body>
    <h1>integration</h1>
    <a href="<c:url value="/people/"/>">Contact List</a><br>
    <a href="<c:url value="/accounts/"/>">Account List</a><br>
</body>
</html>

锚 URL 不包括根上下文。c:url标签将为您处理此问题。

web.xml将映射更改为：

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

如果 Web 应用程序中的所有内容都由 Spring MVC 控制，通常不需要单独映射控制器。

并像这样映射你@Controllers：

@Controller
@RequestMapping("/people")
public class PersonController {

    @RequestMapping("/")
    public String listPeople(Map<String, Object> map) {
        ...
        return "people";
    }

}

我在这里所做的就是丢失for的尾随/。@RequestMapping/people
