Spring cache 配置代理 改为aspectj

 

1 Spring cache 配置代理 改为aspectj

1.1 使用配置

1)  添加依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.3.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-instrument</artifactId>
</dependency>

 

2) Spring xml配置

<context:load-time-weaver />
<context:component-scan base-package="com.xxx.examples"/>
<cache:annotation-driven cache-manager="cacheManager" mode="aspectj"/>

<!--  spring cache with jdk map -->
<bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
    <property name="caches">
        <set>
            <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="default"/>
            <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="product"/>
        </set>
    </property>
</bean>

 

3) 添加aop.xml

apo.xml  名称固定，位置放在CLASSPATH 下的META-INF/aop.xml

<aspectj>
    <weaver options="-verbose -showWeaveInfo">
        <include within="com.xxx.examples.cache..*"/>
    </weaver>
</aspectj>

 

4) 编写缓存使用代码

如：

 

5) 启动方式

因为使用的aspect 加载时候 改变字节码，所以启动方式Vm上要加个VM 参数

 

-javaagent:C:\Users\xxx\.m2\repository\org\springframework\spring-instrument\4.3.5.RELEASE\spring-instrument-4.3.5.RELEASE.jar

下图是我的main 方法：

public static void main(String[] args) {    ApplicationContext ctx = new ClassPathXmlApplicationContext("context-business-cache.xml");    ProductService productService = ctx.getBean(ProductService.class);    productService.queryByIdOut("1");    productService.queryByIdOut("1");}

下图是我运行的结果：

查询DB16:47:20.858 [main] DEBUG org.terracotta.offheapstore.paging.UpfrontAllocatingPageSource - Allocating a 1MB buffer from chunk 0 &52323942416:47:20.859 [main] DEBUG org.terracotta.offheapstore.paging.OffHeapStorageArea - Data area expanded from 1MB to 2MB [occupation=0.0]

只查询了一次db 说明我的配置已经生效
