SpringMVC/Hibernate项目实践一
SpringMVC/Hibernate项目实践二
SpringMVC/Hibernate项目实践三
第一步,引入SpringMVC实现控制层
pom.xml中引入依赖包:
<properties>

web.xml参考内容:

<!-- Spring MVC 的配置结束 -->
</web-app>
- 在src/main/resources中创建spring-mvc.xml
spring-mvc.xml参考代码:
<?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/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">
<!-- 自动扫描且只扫描 @Controller -->
<context:component-scan base-package="online.shixun.project"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:include-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan>
<!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 构建一个默认的 Serlvet 来额外的处理一切静态资源 -->
<mvc:annotation-driven />
<mvc:default-servlet-handler />
</beans>
- 创建包controller,创建controller的类
UserController.java
@Controller
public class UserController {
@RequestMapping(value="hello")
public String hello(){
return "hello";
}
}
- 在src/main/webapp/WEB-ING中创建views文件夹,在里面创建hello.jsp
