1、创建Maven工程,在pom.xml文件上添加
xml version="1.0" encoding="UTF-8"?> project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> modelVersion>4.0.0modelVersion> groupId>org.javaboygroupId> artifactId>xmlssmartifactId> version>1.0-SNAPSHOTversion> packaging>warpackaging> dependencies> dependency> groupId>org.springframeworkgroupId> artifactId>spring-webmvcartifactId> version>5.1.6.RELEASEversion> dependency> dependencies> project>
2、在resources文件下创建两个 .xml 配置文件,一个是对应 spring 的配置文件 applicationContext.xml ,另一个是对应 springmvc 的配置文件 spring-servlet.xml ;
applicationContext.xml 配置文件中要配置开启包扫描,开启过滤器,但开启的包扫描设置成不扫描controller层;
xml version="1.0" encoding="UTF-8"?> beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> context:component-scan base-package="org.javaboy" use-default-filters="true"> context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> context:component-scan> beans>
spring-servlet.xml 配置文件中要配置开启包扫描,不开启过滤器,但开启的包扫描只扫描controller层,并开启注解扫描;
xml version="1.0" encoding="UTF-8"?> beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> context:component-scan base-package="org.javaboy" use-default-filters="false"> context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> context:component-scan> mvc:annotation-driven/> beans>
3、构建web.xml
4、在 web.xml 中配置Filter、Listener、Servlet等
xml version="1.0" encoding="UTF-8"?> web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0"> context-param> param-name>contextConfigLocationparam-name> param-value>classpath:applicationContext.xmlparam-value> context-param> listener> listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class> listener> servlet> servlet-name>springmvcservlet-name> servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class> init-param> param-name>contextConfigLocationparam-name> param-value>classpath:spring-servlet.xmlparam-value> init-param> servlet> servlet-mapping> servlet-name>springmvcservlet-name> url-pattern>/url-pattern> servlet-mapping> web-app>
5、创建controller
@RestController public class HelloController { @Autowired HelloService helloService; @GetMapping(value = "/hello",produces = "text/html;charset=utf-8") public String hello(){ return helloService.hello(); } }
6、创建service
@Service public class HelloService { public String hello() { return "爪洼男孩"; } }
7、配置tomcat
第一次配置时,需要选择图2中的 Configure... 选择 Tomcat 安装的位置
点击 Deployment 然后再点击右边的 “+” 然后再点击第一个,选择 war,最后OK
启动tomcat,访问http://localhost:8080/hello
