Question

你可以帮我解释为什么我的控制器＆＃39;处理程序方法无法正确运行，即在应用程序上载期间正确映射，在运行阶段找不到它们，例如，来自日志

...
RequestMappingHandlerMapping - Mapped "{[/searchModel],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String CLASS_NAME.METHOD()
...
[main] org.apache.catalina.startup.Catalina.start Server startup in 16212 ms
...
RequestMappingHandlerMapping : Looking up handler method for path /searchModel
RequestMappingHandlerMapping : Did not find handler method for [/searchModel]
...

是否存在配置缺失的问题，或者我的代码更深入？

控制器代码

@Controller
public class SearchModelController {
    ...
    @Autowired
    private SearchModelDAO searchModelDAO;
    ...
    @RequestMapping(value = "/searchModel", method = RequestMethod.GET)
    public String METHOD()
    {
        return "searchModelForm.html";
    }
    ...

除了方法和两个@Autowired之外，控制器的代码并不多。完成所有必要的导入。

应用程序main用

定义

@SpringBootApplication
public class Application extends SpringBootServletInitializer
{
    @SuppressWarnings("resource")
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
    {
        new ClassPathXmlApplicationContext("CONTEXT.xml");
        return application.sources(Application.class);
    }

CONTEXT.xml

<!-- <?xml version="1.0" encoding="UTF-8"?> -->
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

...

web.xml是

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

    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value></param-value>
</context-param>

代码在Eclipse下用Maven编译并生成WAR包。然后我把.war放在apache webapps目录下并启动apache。

谢谢

处理程序方法首先映射，而不是找不到
