Koala平台的业务日志子系统是基于Maven的项目模块，最方便的集成是项目也使用Maven，war项目集成请自行下载jar包

前提

依赖spring

添加仓库

    		
     			
      
       koala-releases
      			
      
       http://nexus.openkoala.org/content/repositories/public-releases/
      			
      				
       
        true
       			
      			
      				
       
        false
       			
      		
     		
     			
      
       koala-snapshots
      			
      
       http://nexus.openkoala.org/content/repositories/public-snapshots/
      			
      				
       
        false
       			
      			
      				
       
        true
       			
      		
     	
    

添加依赖

    			
     
      org.openkoala.businesslog
     			
     
      koala-businesslog-api
     			
     
      3.0.0
     		
    		
    			
     
      org.openkoala.businesslog
     			
     
      koala-businesslog-impl
     			
     
      3.0.0
     		
    

根据项目实际分层情况添加依赖到对应的pom.xml，Koala项目把依赖添加到application-impl层

创建LogFilter类

例如com.xiaokaceng.demo.web.controller.businesslog.LogFilter.java

package com.xiaokaceng.demo.web.controller.businesslog;import org.openkoala.businesslog.utils.BusinessLogServletFilter;import javax.servlet.*;public class LogFilter extends BusinessLogServletFilter {    /**     * 将需要用到的信息放入日志上下文     *     * @param req     * @param resp     * @param chain     */    @Override    public void beforeFilter(ServletRequest req, ServletResponse resp, FilterChain chain) {        addIpContext(getIp(req));        // TODO 需要自己实现获取用户名        addUserContext("xxx");    }    public void init(FilterConfig filterConfig) throws ServletException {        //To change body of implemented methods use File | Settings | File Templates.    }    public void destroy() {        //To change body of implemented methods use File | Settings | File Templates.    }}

注意：当前用户需根据系统实现来获取

配置web.xml

        
    		
     
      LogFilter
     		
     
      com.xiaokaceng.demo.web.controller.businesslog.LogFilter
     	
    	
    		
     
      LogFilter
     		
     
      /*
     	
    

类路径下创建koala-businesslog.properties

pointcut=execution(* org.openkoala.example.application.impl.*.*(..))#日志开关kaola.businesslog.enable=true#日志导出器businessLogExporter=org.openkoala.businesslog.utils.BusinessLogExporterImpl#数据库设置log.db.jdbc.driver=${db.jdbcDriver}log.db.jdbc.connection.url=${db.connectionURL}log.db.jdbc.username=${db.username}log.db.jdbc.password=${db.password}log.db.jdbc.dialect=${hibernate.dialect}log.hibernate.hbm2ddl.auto=${hibernate.hbm2ddl.auto}log.hibernate.show_sql=${hibernate.show_sql}log.db.Type=${db.Type}db.generateDdl=${generateDdl}log.maximumConnectionCount=3000log.minimumConnectionCount=100#线程池配置#核心线程数log.threadPool.corePoolSize=100#最大线程数log.threadPool.maxPoolSize=3000#队列最大长度log.threadPool.queueCapacity=2000#线程池维护线程所允许的空闲时间log.threadPool.keepAliveSeconds=300#线程池对拒绝任务(无线程可用)的处理策略log.threadPool.rejectedExecutionHandler=java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy

pointcut(切入点)：通过切面记录业务日志 

businessLogExporter(业务日志输出)：指定采用那种方式输出，默认输出是记录到数据库，可扩展BusinessLogExporter接口实现自定义输出

整合业务功能

例如某接口实现类PersonInfoApplicationImpl.java，需要对新增、删除方法进行业务日志记录。代码如下：

@MethodAlias("save")	public PersonInfoDTO savePersonInfo(PersonInfoDTO personInfoDTO) {		PersonInfo personInfo = new PersonInfo();		try {        	BeanUtils.copyProperties(personInfo, personInfoDTO);        } catch (Exception e) {        	e.printStackTrace();        }		personInfo.save();		personInfoDTO.setId((java.lang.Long)personInfo.getId());		return personInfoDTO;	}       @MethodAlias("remove")	public void removePersonInfo(Long id) {		this.removePersonInfos(new Long[] { id });	}

在需要记录的业务日志的方法上打上@MethodAlias的注解，value的值必须是唯一的，命名规则必须符合java方法命名

• 类路径下创建businessLogConfig文件夹

用于存放处理业务日志的groovy文件

• businessLogConfig文件夹下创建groovy文件

文件名可以随意，只要符合java类命名规则。如PersonInfoApplicationImpl.groovy

package vm.other.businesslog_resources.businessLogConfigclass PersonInfoApplicationImpl {    def context    def save() {        "${getPreTemplate()}:创建个人信息,名字为:${context._param0.name}"    }        def remove() {        "${getPreTemplate()}:删除个人信息"    }        def getPreTemplate(){        "${context._user}-"    }}

这里的方法名必须与@MethodAlias的value一一对应

• 引入Spring配置

<import resource="classpath*:koala-businesslog-aop.xml"></import>

<import resource="classpath*:koala-businesslog-shared-persistence.xml"></import>

• 添加packagesToScan

<value>org.openkoala.businesslog.model</value>
