Spring 基于 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
Spring mvc Java based Configuration not working. Console display no error but my jsp page is not showing
您好，我正在将我的简单演示项目从 bean 配置转换为纯 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。这些是我获取代码的网站。

对于休眠，我使用了本教程
http://websystique.com/spring/spring4-hibernate4-mysql-maven-integration-example-using-annotations/
我的class是
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.MvcConfigurtion
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
包裹 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[] { "/" };
}
}
只添加了这些新的 class。我删除了我的 web.xml。
稍后我会添加Spring安全配置class
这是我的控制台输出

感谢您的回答。我发现了问题。当我在我的 MvcConfiguration class 上写 @ComponentScan 时，它起作用了，页面正在显示。
