spring集成mongodb通过aop记录业务日志

1. 编辑 pom.xml 添加 maven 依赖

<!-- mongodb -->
        <dependency>
          <groupId>org.mongodb</groupId>
          <artifactId>mongo-java-driver</artifactId>
          <version>2.14.2</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.data</groupId>
          <artifactId>spring-data-mongodb</artifactId>
          <!-- 都是坑，用最新版的报错，下面全部用回1.7.1版 -->
          <version>1.7.1.RELEASE</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.data</groupId>
          <artifactId>spring-data-mongodb-cross-store</artifactId>
          <version>1.7.1.RELEASE</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.data</groupId>
          <artifactId>spring-data-mongodb-log4j</artifactId>
          <version>1.7.1.RELEASE</version>
        </dependency>
        <!-- mongodb -->

2.添加 spring-mongodb.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mongo="http://www.springframework.org/schema/data/mongo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

    <!--连接池配置-->
    <mongo:mongo id="mongo" host="host" port="port">
        <mongo:options connections-per-host="8"
                       threads-allowed-to-block-for-connection-multiplier="4"
                       connect-timeout="1000"
                       max-wait-time="1500"
                       auto-connect-retry="true"
                       socket-keep-alive="true"
                       socket-timeout="1500"
                       slave-ok="true"
                       write-number="1"
                       write-timeout="0"
                       write-fsync="true"/>
    </mongo:mongo>

    <!--连接池工厂配置-->
    <mongo:db-factory dbname="dbname" username="username" password="pwd" mongo-ref="mongo"/>

    <!-- MongoDBTemplate -->
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
    </bean>
</beans>

3.在 applicationContext.xml 文件中引用 spring-mongodb.xml

<import resource="spring-mongodb.xml" />

4.若 aop 在controller 层不生效，则需要在 springmvc 配置文件添加如下配置

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

5.集成 MongoTemplate
