Java Spring mvc异常中的空servlet名称
我在spring mvc中遇到了下一个问题 以下是我想测试的控制器中的方法:Java Spring mvc异常中的空servlet名称,java,spring,spring-mvc,freemarker,servletexception,Java,Spring,Spring Mvc,Freemarker,Servletexception,我在spring mvc中遇到了下一个问题 以下是我想测试的控制器中的方法: @Controller @RequestMapping("/groups") public class GroupController { @Autowired private GroupService groupService; @RequestMapping(method = RequestMethod.GET) public String getGroups() {
@Controller
@RequestMapping("/groups")
public class GroupController {
@Autowired
private GroupService groupService;
@RequestMapping(method = RequestMethod.GET)

Spring配置文件

我在控制器中有更多的方法和更多的测试,但只有1个不起作用。我有以下例外:
javax.servlet.ServletException:无法解析名为“”的servlet中名为“”组“”的视图
为什么servlet名称为空?当我运行应用程序时,cotroller中的getGroups方法工作正常,但未通过测试
当我将视图解析器从ftl更改为jsp时
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
它与这个视图解析器完美配合。我看不出您是如何加载spring配置文件的。请使用web.xml加载spring配置文件,这可能会解决您的问题
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>your spring config file location</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
我通过Intellij idea中的facets加载配置文件。我试着像你一样更改我的web.xml,但没有成功
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>your spring config file location</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
