SpringMvc环境搭建Demo

新建WEB项目，WEB-INF下创建lib文件夹，导入jar包：

其中的jackson-core和jackson-mapper为@ResponseBody注解的依赖jar包

如果需要连接数据库需要导入数据库驱动包，tomcat的lib目录下也需要导入数据库的jar包

web.xml配置文件：

spring

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath*:config/spring-*.xml

1

spring

*.do

src目录下新建web.xml配置文件中的config目录，

创建spring-servlet.xml配置文件：

xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:tx="http://www.springframework.org/schema/tx"

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-3.2.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-3.2.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.2.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

注解扫描要注意需要扫描全部使用注解的包，否则error create bean

测试环境：

ApplicationContext context = new ClassPathXmlApplicationContext("/conf/springmvc-servlet.xml");

DemoController controller = (DemoController) context.getBean("demoController");

System.out.println(controller);
