Question

我正在尝试创建spring应用程序。我在启动tomcat服务器时遇到错误。有谁可以帮我找出这个问题的原因？

Answer 1

您应该检查您的依赖项。一个问题是你的spring-test依赖：它有一个旧的不兼容版本，它不在范围测试中！

ResourceEditor在2.5和4.2之间变化，旧的构造函数ResourceEditor(ResourceLoader)不再可用，而是ResourceEditor(ResourceLoader,PropertyResolver)。

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-test</artifactId>
  <version>4.2.5.RELEASE</version>
  <scope>test</scope>
</dependency>

在您当前的设置中，我假设您的依赖项中将有两个版本的Spring框架（2.5和4.2.5）。在更改上面的mvn dependency:tree依赖项之前和之后，请查看spring-test。

如果您的家属已经打了折扣，我建议您从https://start.spring.io/构建一个Web项目框架，将其导入您的工作区并检查pom.xml的Dependency Hiearchy选项卡。

参见示例：inputs to generate a spring mvc 4.2.5 tomcat 7 project test，hibernate ...包含在内配置，甚至是您的web.xml都是通过注释初始化的。你可以通过注释初始化来避免spring-servlet，
Exmanple Hibernate：

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.yourpackage.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {`` 

    @Autowired
    private Environment environment;

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

    @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;
    }

    private 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.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        return properties;        
    }

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

对于viewResolver：

@Configuration
@ComponentScan(basePackages="com.yourpackage")
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{

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

使用Dependency Hiearchy作为参考，以确保您没有遗漏任何依赖对于tomcat，您可以省略dependecies，因为您有本地服务器。
