Question

我使用spring java configs创建一个Web应用程序。

当我在tomcat上运行时，它说资源/ myapp / myapp未找到

在控制台输出中，我注意到以下内容。我不确定这是否会导致任何问题。

我只显示那些奇怪的日志行。因为日志太大了

这是WebAppContextConfig.java

package com.example;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.example")
public class WebAppContextConfig extends WebMvcConfigurerAdapter{
//Resolve logical view names to .jsp resources in /WEB-INF/views directory

@Bean
public InternalResourceViewResolver configureInternalResourceViewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/scripts/**").addResourceLocations("/scripts/");
    registry.addResourceHandler("/css/**").addResourceLocations("/css/");
    registry.addResourceHandler("/images/**").addResourceLocations("/images/");
}
}

这是WebAppInitializer.java

 package com.example;

 import javax.servlet.ServletContext;
 import javax.servlet.ServletException;
 import javax.servlet.ServletRegistration;

 import org.springframework.context.annotation.ComponentScan;
 import org.springframework.web.WebApplicationInitializer;
 import org.springframework.web.context.ContextLoaderListener;
 import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
 import org.springframework.web.servlet.DispatcherServlet;
 import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;

 public class WebAppInitializer implements WebApplicationInitializer {

/* (non-Javadoc)
 * @see org.springframework.web.WebApplicationInitializer#onStartup(javax.servlet.ServletContext)
 */
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
    rootContext.register(WebAppContextConfig.class);
    servletContext.addListener(new ContextLoaderListener(rootContext));

      AnnotationConfigWebApplicationContext dispatcherContext = 
                new AnnotationConfigWebApplicationContext();
              dispatcherContext.register(WebAppContextConfig.class);

    ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext));
    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/");


    DefaultServletHandlerConfigurer defaultConfig = new DefaultServletHandlerConfigurer(servletContext);
    defaultConfig.enable();

}

}

还有什么好地方可以找到基于java的spring mvc配置吗？

这不是@ravi的根本原因，但我确实看到了一些我想要强调的问题：

一个。您似乎通过ContextLoaderListener和Dispatcher servlet两次加载Spring Java Config文件，只通过ContextLoaderListener执行，您可以通过这种方式定义DispatcherServlet - 只需加载一个空上下文（理想情况下有两个java配置 - 一个用于核心应用程序，一个用于Web配置）：

ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new GenericWebApplicationContext());
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");

湾你能用log4j启用调试模式并查看还记录了什么 - 如果这不是足够的信息，请记录跟踪级别。

℃。内部视图解析器路径看起来有点不对 - 你错过了前进“/”：

resolver.setPrefix("/WEB-INF/jsp/");

请你试试这些，看看你现在看到了什么。
