Struts 整合 SpringMVC

Struts 整合 SpringMVC 过程：这篇文章是我在整合过程中所做的记录和笔记

web.xml ：筛选器机制过滤

• 原机制是拦截了所有 url ，即 /*

• 新机制为了将 structs2 的 url 与 SpringMVC 的 url 区分开来，则修改了拦截属性

   
        struts2
        /*
        REQUEST  
        FORWARD 
    
    
    

   
        struts2
        *.action
        REQUEST 
        FORWARD 
    
    
        struts2
        *.jsp
        REQUEST  
        FORWARD 
    

web.xml struts 整合 SpringMVC

     
    
        contextClass
        
            org.springframework.web.context.support.AnnotationConfigWebApplicationContext
        
    
    
    
        contextConfigLocation
        spring.config.AppConfig
    
    
    
        org.springframework.web.context.ContextLoaderListener
    
    
    
        dispatcher
        org.springframework.web.servlet.DispatcherServlet
        
        
            contextClass
            
                org.springframework.web.context.support.AnnotationConfigWebApplicationContext
            
        
        
        
            contextConfigLocation
            spring.config.MvcConfig
        
    
    
    
        dispatcher
        /km/*
    
    

• 基于web.xml配置文件的配置属性，需要配置两个Config类：【两个配置的区别】

  • AppConfig.java

  @Configuration
  @Import({KmAppConfig.class})
  public class AppConfig {
  
  }

  • MvcConfig.java

  @Configuration
  @Import({KmMvcConfig.class})
  public class MvcConfig {
  
  }

• 基于Config类，配置具体的应用Config

  • KmAppConfig.java

  @Configuration
  @ComponentScan(basePackages = "com.teemlink.km.") //扫描包体
  public class KmAppConfig implements TransactionManagementConfigurer,ApplicationContextAware {
  private static ApplicationContext applicationContext;
  
  @Autowired
  private DataSource dataSource;
  @Override
  public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
      KmAppConfig.applicationContext = applicationContext;
  }
  public static ApplicationContext getApplicationContext() {
      return applicationContext;
  }
  
  @Bean
  public DataSource dataSource() {
      //如何读取配置资源的数据?
      String url = "jdbc:jtds:sqlserver://192.168.80.47:1433/nj_km_dev";
      String username = "sa";
      String password = "teemlink";
      DriverManagerDataSource ds = new DriverManagerDataSource(url, username, password);
      ds.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");
      return ds;
  }
  
  @Bean
  public JdbcTemplate jdbcTemplate(DataSource dataSource){
      return new JdbcTemplate(dataSource);
      
  }
  @Override
  public PlatformTransactionManager annotationDrivenTransactionManager() {
      return new DataSourceTransactionManager(dataSource);
  }
  }

  • KmMvcConfig.java

  @Configuration
  @EnableWebMvc
  @ComponentScan(basePackages = "com.teemlink.km.**.controller")
  public class KmMvcConfig extends WebMvcConfigurerAdapter {
      @Override
      public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
          configurer.enable();
      }
  }

基于SpringMVC 的 Controller - Service - Dao 框架

• AbstractBaseController

  /**
   * 抽象的RESTful控制器基类
   * @author Happy
   *
   */
  @RestController
  public abstract class AbstractBaseController {
      
      @Autowired  
      protected HttpServletRequest request;
      
      @Autowired
      protected HttpSession session;
      
      protected Resource success(String errmsg, Object data) {
          return new Resource(0, errmsg, data, null);
      }
      
      protected Resource error(int errcode, String errmsg, Collection
