关于Spring mvc 注解 拦截器实现 log 功能

前两天 项目 快要结尾的时候，我们需要 程序 需要 完善一个log 日志记录 。 日志记录 由拦截器 每次触发，log 每次 记录到 数据库中，  接下来是 注解代码的实现 和配置文件。。

 

首先 配置  数据库连接 文件。  persistence.xml

 

"

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">

<persistence-unit name="sxm_cpbh" transaction-type="RESOURCE_LOCAL">// 数据持久化的 名称  数据持久化的类型

 

 <provider>org.hibernate.ejb.HibernatePersistence</provider> //hibernate持久化

       <properties>
            <property name="hibernate.connection.driver_class"
                      value="oracle.jdbc.driver.OracleDriver"/> //数据库驱动名称
          
            <property name="hibernate.connection.url" 
                      value="jdbc:oracle:thin:@192.168.96.251:1521:~~~~"/>//数据库 名称 url
            <property name="hibernate.connection.username" value="~~~~"/>
            <property name="hibernate.connection.password" value="~~~~"/>
            <property name="hibernate.dialect"
                      value="org.hibernate.dialect.Oracle10gDialect"/> // 方言

            <property name="hibernate.show_sql" value="true"/> //执行 时显示 sql语句

 

  </persistence-unit>

</persistence>

"

 

  接下来是 Spring-mvc.xml 的 配置

<!-- 自动扫描包下的所有类，使其认为spring mvc的控制器 -->
<context:component-scan base-package="com.cmcc.*"/>

    <aop:aspectj-autoproxy proxy-target-class="true"/>

//当配为<aop:aspectj-autoproxy 
poxy-target-class="true"/>时，表示使用CGLib动态代理技术织入增强。不过即使proxy-target-class设置为false，如果目标类没有声明接口，则spring将自动使用CGLib动态代理。
