1、增加修改和删除的功能
allBook.jsp
<c:forEach var="book" items="${list}"> <tr> <td>${book.bookid}</td> <td>${book.bookname}</td> <td>${book.bookcount}</td> <td>${book.dateail}</td> <td> <a href="${pageContext.request.contextPath}/book/updateBooks?id=${book.bookid}">修改</a> | <a href="${pageContext.request.contextPath}/book/deleteBook/${book.bookid}">删除</a> </td> </tr> </c:forEach>
//修改书籍 @RequestMapping("/updateBook") public String updatebook(Books books){ System.out.println("updateboos=>"+books); int i=bookService.updatebook(books); if (i>0){ System.out.println("添加成功"+books); } return "redirect:/book/allBook"; }
updateBooks.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>修改书籍</title> <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"> <div class="row clearfix"> <div class="col-md-12 column"> <div class="page-header"> <h1> <samp>修改数据</samp> </h1> </div> </div> <form action="${pageContext.request.contextPath}/book/updateBook" method="post"> <%--出现的问题，提交了sql请求，，但是是修改失败，再次考虑，是事务的问题，配备完毕依旧失败 看一下sql语句能否执行成功，发现sql执行失败，修改为未完成 解决方法： 前端传递隐藏域--%> <input type="hidden" name="bookid" value="${sbook.bookid}"> <div class="form-group"> <label >书籍名称:</label> <input type="text" name="bookname" class="form-control" value="${sbook.bookname}" required > </div> <div class="form-group"> <label >书籍数量:</label> <input type="text" name="bookcount" class="form-control" value="${sbook.bookcount}" required > </div> <div class="form-group"> <label >书籍描述:</label> <input type="text" name="dateail" class="form-control" value="${sbook.dateail}" required > </div> <div class="form-group"> <input type="submit" class="btn btn-success form-control" value="修改"> </div> </form> </div> </div> </body> </html>
spring-service.xml 配置事务
<?xml version="1.0" encoding="UTF-8" ?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--1、扫描service下的包--> <context:component-scan base-package="com.zy.service"/> <!--2、将我们的所有业务类，注入到spring，可以通过配置或者通过注解实现--> <bean id="BookServiceImpl" class="com.zy.service.BookServiceImpl"> <property name="bookMapper" ref="bookMapper"/> </bean> <!--3、声明式事务配置--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!--注入数据源--> <property name="dataSource" ref="dataSource"/> </bean> <!--4、aop事务支持--> <!--结合aop，实现事务的织入--> <!--配置事务通知：--> <!-- 配置事务管理器 --> <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 配置事务属性 --> <tx:advice id="txAdvice" transaction-manager="TransactionManager"> <tx:attributes> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <!--配置事务切入--> <aop:config> <aop:pointcut id="txPointCut" expression="execution(* com.zy.dao.*.*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/> </aop:config> </beans>
在设置一个日志，更好的看到后台输出的sql语句
mybatis-config.xml
<!--配置日志--> <settings> <setting name="logImpl" value="STDOUT_LOGGING"/> </settings>
//删除书籍 @RequestMapping("/deleteBook/{bookid}") public String deletebook(@PathVariable("bookid") int id){ bookService.deletebook(id); return "redirect:/book/allBook"; }
显示结果：
