通过javaConfig来配置config,并能正常访问url。
先看图
访问地址:http://localhost:8080/gugua5/
http://localhost:8080/gugua5/helloagain
先看下pom.xml

额外说下,build配置
首先要注意这里maven-war-plugin 插件的声明。正如我们将完全删除web.xml ,我们需要配置这个插件,以避免Maven构建war包失败。第二个变化是加入了JSP/Servlet/Jstl 的依赖关系,这些我们可能需要,因为我们将要使用 servlet API和JSTL视图在我们的代码中.
<build> <!-- javaConfig配置 --> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.6</version> <configuration> <!-- jsp目录 --> <warSourceDirectory>src/main/webapp</warSourceDirectory> <!-- 项目名/url --> <warName>gugua5</warName> <!-- 取消xml配置:web.xml/applicationContext.xml/xxx-servlet.xml --> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </pluginManagement> <finalName>gugua5</finalName> </build>
HelloController.java
package springmvc.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.ui.ModelMap; @Controller @RequestMapping(value="/") public class HelloWorldController { @RequestMapping(method=RequestMethod.GET) public String sayHello(ModelMap model) { model.addAttribute("greeting", "hello world from spring mvc 4"); return "hello_say"; } @RequestMapping(value="/helloagain", method=RequestMethod.GET) public String sayHelloAgain(ModelMap model) { model.addAttribute("greeting", "hello world again, spring mvc 4"); return "hello_say"; } }
添加配置类
HelloWorldConfiguration.java
在src/main/java下添加下面提到的类指定的包,如下图所示。这种构造类可以被看作是一个替代 spring-servlet.xml,因为它包含了所有必需的组件的扫描和视图解析器的信息。
@Configuration指明该类包含注解为@Bean 生产 bean管理是由Spring容器的一个或多个bean方法。
@EnableWebMvc 等同于 mvc:annotation-driven 在XML中. 它能够为使用@RequestMapping向特定的方法传入的请求映射@Controller-annotated 类。
@ComponentScan 等同于 context:component-scan base-package="..." 提供 spring 在哪里寻找 管理 beans/classes.
package springmvc.configuration; 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.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; @Configuration @EnableWebMvc @ComponentScan(basePackages="springmvc") public class HelloWorldConfiguration { @Bean public ViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setViewClass(JstlView.class); viewResolver.setPrefix("/WEB-INF/views/"); viewResolver.setSuffix(".jsp"); return viewResolver; } }
添加一个初始化类实现 WebApplicationInitializer 在src/main/java 中使用如下图所示指定包(在这种情况下,作为替代在 web.xml 中定义的任何 Spring 配置)。在Servlet 3.0的容器启动时,这个类将被加载并初始化,并在启动由servlet容器调用方法。
package springmvc.configuration; import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; public class HelloWorldInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { @Override protected Class<?>[] getRootConfigClasses() { // TODO Auto-generated method stub return new Class[] { HelloWorldConfiguration.class }; } @Override protected Class<?>[] getServletConfigClasses() { // TODO Auto-generated method stub return null; } @Override protected String[] getServletMappings() { // TODO Auto-generated method stub return new String [] { "/" }; } }
