No mapping found for HTTP request with URI [/...] in DispatcherServlet with name ...的解决方法

    我在搭建一个Lucene的项目时遇到了这个问题：No mapping found for HTTP request with URI [/myLucene1/index.do] in DispatcherServlet with name 'spring'

    产生原因： IndexController类里没有加controller的注解。如下：

...

import org.springframework.web.bind.annotation.RequestParam;
import org.wltea.analyzer.lucene.IKAnalyzer;

public class IndexController {
public static String INDEX_PATH = "C:/Users/Administrator/Desktop/testSearchEngineDemo/createdIndex";
public static String DATA_PATH = "C:/Users/Administrator/Desktop/testSearchEngineDemo/data";
public static Analyzer ANALYZER = new IKAnalyzer();

        .....

}

    解决办法：在 IndexController类里加上“@Controller”。如下：

...

import org.springframework.web.bind.annotation.RequestParam;
import org.wltea.analyzer.lucene.IKAnalyzer;

@Controller
public class IndexController {
public static String INDEX_PATH = "C:/Users/Administrator/Desktop/testSearchEngineDemo/createdIndex";
public static String DATA_PATH = "C:/Users/Administrator/Desktop/testSearchEngineDemo/data";
public static Analyzer ANALYZER = new IKAnalyzer();
...

}
