Question

我在搜索领域有一些谷歌关于我的问题，但我没有得到解决方案。在spring项目（不启动）中通过maven创建intellij想法我设置了所有东西（见下文），如tomcat配置，java配置简单helloWorld等...但是：我得到的结果只有爆炸战争而不是欢迎目录：我在localhost：8080（不是在localhost：8080 / welcome）看到它。如果我将工件设置为战争，我会得到通常的tomcat主页，而不是我的项目。

下面的代码片段：

控制器：

package com.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String welcome(Model model){
        model.addAttribute("hello", "Hello");
        model.addAttribute("anyone", "anyone");
        return "welcome";
    }
}

WebApplicationContextConfig：




package com.config;

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.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;


@Configuration
@EnableWebMvc
@ComponentScan("com")
public class WebAppContextConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public InternalResourceViewResolver getInternalViewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/pages/");
        resolver.setSuffix(".jsp");

        return resolver;
    }
}


package com.config;

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.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;


@Configuration
@EnableWebMvc
@ComponentScan("com")
public class WebAppContextConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public InternalResourceViewResolver getInternalViewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/pages/");
        resolver.setSuffix(".jsp");

        return resolver;
    }
}

DispatcherServletInitializer：

的pom.xml：

package com.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;


public class DispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{WebAppContextConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

我建议你不要打扰自己使用Spring配置文件，并使用已经为你配置的Spring Boot。

例如，这个'hello world'样本应该做你想做的事：https://github.com/pgrimard/spring-boot-hello-world

另外，请考虑http://start.spring.io/生成项目的骨架。

Spring + Maven + Intellij + HelloWorld
