SSM框架配置文件整合

1 web.xml

• 1.1前端控制器

  springmvc
  
      org.springframework.web.servlet.DispatcherServlet
  
      
  
      contextConfigLocation
      classpath:springmvc-config.xml
  
  
  1



  springmvc
  *.action

ps: classpath是WEB-INF下的classes文件路径，在工程项目下新建config,内部的文件会自动加载到classes文件下，需要在navigator视图下才能看得到。（这是在.clsspath配置里设置的）

• 1.2配置编码过滤器

    
    
        CharacterEncodingFilter      
        
            org.springframework.web.filter.CharacterEncodingFilter
        
        
            encoding
            UTF-8
        
    
    
        CharacterEncodingFilter
        /*
    

• 1.3事物传播行为以及切面配置

2.springmvc-config.xml

• 2.1 配置控制器扫描

• 2.2配置视图控制器

• 2.3配置自定义类型转换器

• 2.4配置注解驱动

配置了扫描就不需要配置主注解驱动了 原因如下

1>会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean
        DefaultAnnotationHandlerMapping ：负责扫描带有@Controller注解的类，给此类设置对应的@RequestMapping
        AnnotationMethodHandlerAdapter ：负责扫描Controller类中的方法，给方法设置对应的@RequestMapping
2>
        扫描器会扫描带有@Component@Service@Controller@Component等注解，并实现相应的操作，
        因为这四个注解包含了@Controller，
        所以会将Controller类和方法进行映射，不需要用了

• 2.5配置静态资源访问映射

       
     
       
      
      default
      *.jpg
      
         
      
    

• 2.6配置拦截器

拦截器配置

拦截器代码:ps:需要继承HandlerInterceptor接口，并实现三个方法

public class Interceptor1 implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler) throws Exception {
        System.out.println("Intercepter1...preHandle");
        return true;
    }
    @Override
    public void postHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler,
        ModelAndView modelAndView) throws Exception {
        System.out.println("Intercepter1...postHandle");
    }
    @Override
    public void afterCompletion(HttpServletRequest request, 
        HttpServletResponse response, Object handler, 
        Exception ex) throws Exception {
        System.out.println("Intercepter1...afterCompletion");
    }
}

• 2.7配置文件上传解析器

3 db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis
jdbc.username=root
jdbc.password=root
jdbc.maxTotal=30
jdbc.maxIdle=10
jdbc.initialSize=5

4 applicationContext.xml

5 mybatis-config.xml

6 springmvc-config.xml

7 log4j.properties

# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.com.itheima.core=DEBUG
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

8 web.xml配置

    
    
        contextConfigLocation
        classpath:applicationContext.xml
    
    
        
             org.springframework.web.context.ContextLoaderListener
        
    
    
    
        encoding
        
             org.springframework.web.filter.CharacterEncodingFilter
        
        
            encoding
            UTF-8
        
    
    
        encoding
        *.action
    
    
    
        springmvc
        
             org.springframework.web.servlet.DispatcherServlet
        
        
            contextConfigLocation
            classpath:springmvc-config.xml
        
        
        1
    
    
        springmvc
