篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spring mvc + mybatis 整合框架相关的知识,希望对你有一定的参考价值。
首先放几个该放的包(注意:后面两个mybatis-spring-1.1.1.jar mybatis-3.1.1.jar是因为不导入这两个包sql就不会在控制台打印,感觉调试的时候有点不方便,不需要的话就没什么)
下面还有几个包是用来使用json的,就可以直接返回字符串在网页上,如果不导入直接访问方法的话,会返回一个字符串名的jsp
文件目录如下:
接下来就是几个配置文件
applicationContext-dao.xml

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/music
jdbc.username=root
jdbc.password=root
log4j.properties 打印日志的,建议看下log4j日志怎么配置,根据需要来
### set log levels ###
log4j.rootLogger = INFO , stdout
### export Console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.err
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
剩下最后一个,web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Music</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <!-- 支持Restful风格的请求Url --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 过滤中文乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring容器监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置前端控制器 --> <servlet> <servlet-name>Music</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--加载前端控制器配置文件 上下文配置位置 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/mvc-dispatcher-servlet.xml</param-value> </init-param> <!-- 随服务器启动 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Music</servlet-name> <!-- restful风格url --> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
测试是否配置成功:写好controller之后看能否用@controller这种注解,在这里面写一个方法用来测试
run server之后,看打印log日志是否正确,我记得应该出现这种才行
下面试我写的测试controller截图:
运行截图:
这个就算完了,需要用什么功能再导入包,虽然知道maven很方便,但我之前试的时候老是出问题,决定还是采用导入包的形式,勿嫌弃我out了
