java - 基于 Spring mvc Java 的配置不起作用。控制台显示没有错误，但我的 jsp 页面没有显示

Question

您好，我正在将我的简单演示项目从 bean 配置转换为基于纯 java 的配置。 Bean 配置可以很好地创建表和所有内容。但是我的 java 配置没有显示任何页面。我解决了很多错误，但现在控制台没有显示指定问题的错误。这是我的代码，请找出问题所在，或者我是否遗漏了配置中的任何内容。我是 spring 的新手，也是基于 java 的配置的新手。这些是我从中获取代码的网站。

对于 hibernate ，我使用了本教程

http://websystique.com/spring/spring4-hibernate4-mysql-maven-integration-example-using-annotations/

我的课

1. AppConfiguration
 package com.kharoud.configuration;
 import org.springframework.context.annotation.ComponentScan;
 import org.springframework.context.annotation.Configuration;
 import org.springframework.context.annotation.Import;

 @Configuration
 @ComponentScan({"com.kharoud"})
 @Import({MvcConfiguraion.class, RepositoryConfiguration.class})
 public class AppConfiguration {

 }

2.MvcConfiguration

package com.kharoud.configuration;

import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.context.annotation.Bean;
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;


@EnableWebMvc
@Configuration
public class MvcConfiguraion extends WebMvcConfigurerAdapter{


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

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

}
}

3.RepositoryConfiguration 包 com.kharoud.configuration;

import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:hibernate.properties" })
public class RepositoryConfiguration {

@Autowired
private Environment environment;

@Bean
public LocalSessionFactoryBean sessionFactory(){        
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String[] {"com.kharoud.model"});
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;
}

@Bean
public Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect",      environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
    properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
    return properties;
}

@Bean
public DataSource dataSource() {        
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
    return dataSource;
}

@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
   HibernateTransactionManager txManager = new   HibernateTransactionManager();
   txManager.setSessionFactory(s);
   return txManager;
}
}

4.SpringConfigurationInitializer

package com.kharoud.configuration.initilizer;

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

import com.kharoud.configuration.AppConfiguration;


public class SpringConfigurationInitializer extends     AbstractAnnotationConfigDispatcherServletInitializer{

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

@Override
protected Class<?>[] getServletConfigClasses() {
    // TODO Auto-generated method stub
    return null;
}

@Override
protected String[] getServletMappings() {

    return new String[] { "/" };
}

}

只添加了这些新类。我删除了我的 web.xml。

稍后我会添加Spring Security配置类

这是我的控制台输出

我的家庭 Controller

package com.kharoud;

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){
        return "index";
    }
}

myindex.jsp文件在webapp文件夹下的WEB-INF/views文件夹中

The views were properly resolved with bean configuration.

Answer 1

感谢您的回答。我发现了问题。当我在我的 MvcConfiguration 类之上编写 @ComponentScan 时，它起作用了，并且页面正在显示。
