Question

我正在将一个小应用程序从Tomcat / Java 8降级到Tomcat / Java 7.由于这个原因，我不得不将Spring从5.x版降级到4.x版。尽管我正在努力让东西再次运行，但Spring的上下文还没有开始。

配置：

hibernate-entitymanager 5.2.15
mysql-connector-java 6.0.6
javax.servlet-api 4.0.0
jstl 1.2
jta 1.1
spring-data-jpa 2.0.2
commons-codec 1.11
gson 2.8.2
commons-dbcp2 2.2.0
validation-api 2.0.1
spring-core 4.1.4
spring-context 4.1.4
spring-context-support 4.1.4
spring-web 4.1.4
spring-jdbc 4.1.4
spring-orm 4.1.4
spring-webmvc 4.1.4
javax-servlet.jsp-api 2.3.1

问题：

INFO: No Spring WebApplicationInitializer types detected on classpath


package com.mycompany.myapp.conf;

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

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

public class ApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext container) throws ServletException {

        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringConfiguration.class);
        ctx.setServletContext(container);

        ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx));

        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");        
    }

}


package com.mycompany.myapp.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
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(basePackages = "com.mycompany.myapp")
public class SpringConfiguration extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");

        return viewResolver;
    }

    //@Override
     public void addResourceHandlers(ResourceHandlerRegistry registry) {
            registry
              .addResourceHandler("/resources/**")
              .addResourceLocations("/public", "/resources/")
              .setCachePeriod(31556926); 
        }

}

关于知识建设的问题：

我发现Spring没有识别当前的目录结构（显然适用于Java / Tomcat 8和更新版本的Spring）。

然后，我使用常规的Maven目录结构创建了一个新项目，然后Spring开始查看Initializer和Configuration类。

春天没有初始化
