二 配置spring与SpringMVC的配置文件
本例采用servlet 3.0配置文件，不采用web.xml文件，采用java 配置文件进行配置
（一） 配置文件位置
spring与springMVC的配置文件都放置在rbac-web模块中
（二）spring配置文件
spring的配置文件扫描的类，把被Controller、RestController、EnableWebMvc注解标注的类排除掉
package com.ssm.rbac.config; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.ComponentScan.Filter; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.FilterType; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.config.annotation.EnableWebMvc; @Configuration @ComponentScan(basePackages = { "com.ssm.rbac.*" }, excludeFilters = {@Filter(type = FilterType.ANNOTATION, value =Controller.class), @Filter(type = FilterType.ANNOTATION, value =RestController.class), @Filter(type = FilterType.ANNOTATION, value =EnableWebMvc.class)})//启动注解扫描，过滤掉Controller、RestController、EnableWebMvc注解标注的类 public class SpringConfig { }
（三）springMVC的配置文件
SpringMVC配置类，只会扫描被Controller与RestController注解标注的类
package com.ssm.rbac.config; import java.io.IOException; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.ComponentScan.Filter; import org.springframework.http.MediaType; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.FilterType; import org.springframework.stereotype.Controller; import org.springframework.web.accept.ContentNegotiationManager; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.multipart.MultipartResolver; import org.springframework.web.multipart.support.StandardServletMultipartResolver; import org.springframework.web.servlet.View; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer; import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport; import org.springframework.web.servlet.view.ContentNegotiatingViewResolver; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.json.MappingJackson2JsonView; @Configuration // 声明为配置类 @EnableWebMvc // 启动SpringMVC组件。如果在xml配置，也可以采用<mvc:annotation-driven>标签启动 @ComponentScan(basePackages = "com.ssm.rbac.*", useDefaultFilters = false, includeFilters = { @Filter(type = FilterType.ANNOTATION, value = Controller.class), @Filter(type = FilterType.ANNOTATION, value = RestController.class) }) // 启动扫描组件,只扫描Controller与RestController注解标注的bean public class SpringMvcConfig extends WebMvcConfigurationSupport { // 配置视图解析器 @Bean public ViewResolver viewResolver() { InternalResourceViewResolver resolver = new InternalResourceViewResolver(); resolver.setPrefix("/WEB-INF/views/"); resolver.setSuffix(".jsp"); resolver.setExposeContextBeansAsAttributes(true); return resolver; // return new BeanNameViewResolver(); } /** * 配置Multipart数据格式的解析器， 普通的表单提交，提交的时简单的文本数据，如果要提交文件，那么就需要提交的数据时二进制的 * 普通的文本格式数据不支持，而Multipart格式支持，但是DispatcherServlet没有是实现任何解析multipart请求 数据的功能。 * * @return * @throws IOException */ @Bean public MultipartResolver getMultipartResolver() throws IOException { return new StandardServletMultipartResolver(); } // 配置静态资源处理 @Override protected void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { configurer.enable();// 通过调用enable()方法，我们要求DispatcherServlet对静态资源的请求转发到 // Servlet容器中默认的Servlet上，而不是使用DispatcherServlet本身来处理静态资源请求。 } /** * 获得ContentNegotiationManager */ @Override protected void configureContentNegotiation(ContentNegotiationConfigurer configurer) { configurer.defaultContentType(MediaType.APPLICATION_JSON); } /** * 注册内容协商视图解析器 p430 1 确定请求的媒体类型 2 找到适合请求媒体类型的最佳视图 * * @param cnm * @return */ @Bean public ViewResolver cnViewResolver(ContentNegotiationManager cnm) { ContentNegotiatingViewResolver cnvr = new ContentNegotiatingViewResolver(); cnvr.setContentNegotiationManager(cnm); return cnvr; } @Bean public View spittles() { return new MappingJackson2JsonView(); } }
（四）配置org.springframework.web.WebApplicationInitializer接口的实现类
RBACWebApplication类是WebApplicationInitializer接口的实现类，WebApplicationInitializer接口的实现类会被org.springframework.web.SpringServletContainerInitializer加载。
SpringServletContainerInitializer是javax.servlet.ServletContainerInitializer接口的实现类，在Servlet 3.0规范中要求在Servlet 容器一启动就要加载ServletContainerInitializer的实现类。
实现的方式就是采用SPI机制。所以SpringServletContainerInitializer类所在的包会有一个配置文件，如下图所示
下面是启动配置文件
package com.ssm.rbac.config; import javax.servlet.MultipartConfigElement; import javax.servlet.ServletRegistration.Dynamic; import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; public class RBACWebApplication extends AbstractAnnotationConfigDispatcherServletInitializer{ /** * 指定主配置类 */ @Override protected Class<?>[] getRootConfigClasses() { return new Class<?>[] {SpringConfig.class}; } /** * 指定springMVC配置类 */ @Override protected Class<?>[] getServletConfigClasses() { return new Class<?>[] {SpringMvcConfig.class}; } /** * 将一个或者多个路径映射到DispatcherServlet上 */ @Override protected String[] getServletMappings() { return new String[] {"/"}; } /** * 当AbstractAnnotationConfigDispatcherServletInitializer 将DispatcherServlet注册到Servlet容器之后， * 就会调用customizeRegistration方法，并把Servlet注册之后得到的Registration.Dynamic传递过来，通过重写 * customizeRegistration方法，我们可以对DispatcherServlet进行额外的配置 */ @Override protected void customizeRegistration(Dynamic registration) { System.out.println("dispatcherServlet已经注册完成"); //registration.setMultipartConfig(new MultipartConfigElement("/tmp/spitter/")); } }
三 验证
（一）在rbac-manager下创建一个控制器类，如下图所示
代码如下
package com.ssm.rbac.manager.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping(value="/managerController") public class ManagerController { @RequestMapping(value="/componentScanTest") public String componentScanTest( ) { return "success"; } }
（二）访问
访问结果如下
