3、配置IOC和AOP
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 |

1.2 web.xml
配置如下：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |

1.3 springmvc-servlet.xml
只需要配置视图解析器，就可以了，不需要配置视图。因为每一种视图解析都对应一个视图解析。
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 定义jsp视图 beg--> <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/template/"/> <property name="suffix" value=".jsp"></property> </bean> <!-- 定义jsp视图 beg--> </beans> |
1.4 applicationContext
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 加载properties文件 --> <context:property-placeholder location="classpath:config.properties"/> <context:component-scan base-package="web" /> <mvc:annotation-driven/> <!-- 使用@Aspect定义切面 beg --> <aop:aspectj-autoproxy/> <!-- 使用@Aspect定义切面 beg --> <!-- 使用注解@Transactional beg --> <tx:annotation-driven/> <!-- 使用注解@Transactional end --> <!-- 加载dao层相关文件 beg --> <!-- 加载dao层相关文件 end --> </beans> |
如下两个配置必须要在同一个配置文件中
|
1 2 |
<mvc:annotation-driven /> <context:component-scan base-package="com.companyname.workgroup.apply.module.contorller"/> |
2 代码
一个controller的代码如下
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
@Controller public class HelloController { /** * 测试一个velocity * * @return */ @RequestMapping(value = "/helloJsp") public String testVelocity() { return "helloJsp"; } /** * 测试一个json * * @return */ @RequestMapping(value = "/helloJson") @ResponseBody public DemoVo testJson() { DemoVo demo = new DemoVo(); demo.setName("hi"); demo.setStore("23823999"); return demo; } } |
3 IDEA配置tomcat的问题
1、建立Artifacts。 通过“ File -> Project Structure ” ，如下图
自定义name如下：
2、新建tomcat配置
（1）指定tomcat安装目录
（2）指定Artifate
4、启动之后，输入 http://localhost:8080/helloJson ，返回如下结果
|
1 2 3 4 |
{ "name": "hi", "store": "23823999" } |
