404找不到java config spring MVC

我正在spring MVC做一个小项目。我在干净的java上进行的Spring配置就是没有xml。问题是，似乎所有内容都已正确初始化，但由于某种原因容器无法启动并崩溃404.我将为您提供一部分代码：

webconfig.java 

import com.myapp.webapp.Interceptors.AccountInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.*;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@EnableWebMvc
@Configuration
@ComponentScan({"com.myapp.service",
"com.myapp.webapp"
} )
public class WebConfig extends WebMvcConfigurerAdapter {
    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

    @Override
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
        registry.addResourceHandler("/WEB-INF/jsp/**").addResourceLocations("/jsp/");
    }

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

    @Bean
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver resolver=new CommonsMultipartResolver();
        resolver.setDefaultEncoding("utf-8");
        return resolver;
    }

    @Bean
    AccountInterceptor accountInterceptor() {
        return new AccountInterceptor();
    }


    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(accountInterceptor()).addPathPatterns("/account/**");
    }


}

webservletconfiguration.java 

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

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


public class WebServletConfiguration extends AbstractAnnotationConfigDispatcherServletInitializer {

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

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

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

例如控制器 

import com.myapp.model.Account;
import com.myapp.model.Phone;
import com.myapp.service.Service;
import com.myapp.webapp.utils.SetAttributes;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.ServletException;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.ArrayList;
import java.util.List;



@Controller
@SessionAttributes("accountInSession")
@RequestMapping("/account")
public class AccountController {

    @Autowired
    Service<Account> accountService;


    @RequestMapping("/join")
    public ModelAndView join(){
        return new ModelAndView("join");
    }

 // there are many more methods
}

如果我理解正确，那么当我转到http://localhost:8085/webapp-1.0-SNAPSHOT/account/join时，应将其传递到join.jsp，该webapp/WEB-INF/jsp存储在<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>myapp</groupId> <artifactId>socialnet</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <properties> <maven.compile.version>3.3</maven.compile.version> <java.version>1.8</java.version> <h2.version>1.4.194</h2.version> <junit.version>4.12</junit.version> <mysql.version>5.1.17</mysql.version> <dbcp.version>2.1</dbcp.version> <mockito.version>1.9.5</mockito.version> <servlet.version>3.1.0</servlet.version> <maven.deploy.version>2.8.2</maven.deploy.version> <jstl.version>1.2</jstl.version> <tomcat.servler.version>9.0.0.M4</tomcat.servler.version> <spring.version>4.2.3.RELEASE</spring.version> <jquery.version>2.1.4</jquery.version> </properties> <modules> <module>common</module> <module>dao</module> <module>service</module> <module>webapp</module> </modules> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-all</artifactId> <version>${mockito.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>${maven.compile.version}</version> <configuration> <source>${java.version}</source> <target>${java.version}</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <version>${maven.deploy.version}</version> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </build> </project>

webapp中的pom.xml

如果您未在server.contextPath中指定application.properties，则无需在访问应用程序时输入jar / war文件名。

尝试使用http://localhost:8085/account/join＆amp;如果您仍然遇到任何问题，请告诉我。

答案 1 :(得分：0)

您不需要使用war文件夹名称，只需使用您的app名称：

http://localhost: 8085/webapp/account/join

如果您不想使用您的应用名称，则需要将调度程序servlet从/修改为/webapp/，以使您的webapp根文件夹成为根目录
