我有以下控制器......
@Controller
@RequestMapping(value = "/userManagement")
public class UserManagementController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public Object home(Locale locale, Model model) {
logger.info("User management view controller loaded...");
return "userManagement";
}
@RequestMapping(value = "/createUserView", method = RequestMethod.GET)
public Object createUser(Locale locale, Model model) {
logger.info("create controller loaded...");
return "createUser";
}
我的servlet-context设置为以下值...
<beans:bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
现在,如果我转到http://localhost:8080/myapp/userManagement
,那么我会得到视图userManagement.jsp,这正是我想要的......
但如果我去http://localhost:8080/myapp/userManagement/createUserView
我会收到404错误。
NetworkError: 404 Not Found - http://localhost:8080/myapp/userManagement/createUserView"
我没看到的是为什么会发生这种情况,因为我将requestMapping设置为与上面完全相同,并且在/ WEB-INF / views中我有一个createUser.jsp和userManagement.jsp
关于从spring mvc提供意见,我有什么问题吗?
谢谢,
编辑:下面添加了web.xml ...

EDIT2:
另外,如果我直接转到浏览器中的地址而不是使用Ajax(转到myapp / userManagement / createUserView我会收到错误...
HTTP状态404 - /myapp/WEB-INF/views/userManagement/createUserView.jsp因此它看起来看得太高(虽然文件名也错误)。
EDIT3。
好吧,即使我做以下事情,它似乎也是如此..
@Controller
@RequestMapping(value = "/userManagement")
public class UserManagementController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public Object home(Locale locale, Model model) {
logger.info("User management view controller loaded...");
return "createUser";
}
我仍然看到userManagement.jsp页面,因此看起来好像这个返回没有正确触发,但我不知道为什么。记录器的详细信息仍然会被触发到控制台,所以实际上它已到达那里,就像springmvc返回JSP一样奇怪。
答案 0 :(得分:1)
你能检查两件事: 1)向控制器添加断点或查看服务器日志,检查请求是否输入方法。 2)如果第1步没问题,检查jsp是否存在于正确的路径或jsp的名称是否正确
修改强>
等等,如果您使用Ajax请求,您的控制器应该有以下requestMapping:
@RequestMapping(value = "/url", method = RequestMethod.GET,
headers = "X-Requested-With=XMLHttpRequest")
否则您的ajax请求将无法映射,您将获得404。
旁注 你可以将方法返回类型从Object更改为String吗?看看这是否有影响?
答案 1 :(得分:0)
我认为您的web.xml映射不正确,应该是:
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
(注意url-pattern中的/*
)
