Project Integration koala Business Log Subsystem

The Business Log subsystem of the koala platform is a Maven-based project module. The most convenient integration is that Maven is also used for projects. For War Project Integration, please download the jar package by yourself.

Prerequisites

Dependent on Spring

Add Repository

<repositories><repository><id>koala-releases</id><url>http://nexus.openkoala.org/content/repositories/public-releases/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></repository><repository><id>koala-snapshots</id><url>http://nexus.openkoala.org/content/repositories/public-snapshots/</url><releases><enabled>false</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository></repositories>

Add dependency

<dependency><groupId>org.openkoala.businesslog</groupId><artifactId>koala-businesslog-api</artifactId><version>3.0.0</version></dependency><dependency><groupId>org.openkoala.businesslog</groupId><artifactId>koala-businesslog-impl</artifactId><version>3.0.0</version></dependency>

Add the dependency to the corresponding Pom. XML according to the actual project hierarchy. The Koala project adds the dependency to the application-impl layer.

Create a logfilter class

For example, 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 {/*** put the required information into the log context ** @ Param req * @ Param resp * @ Param chain */@ override public void beforefilter (servletrequest req, servletresponse resp, filterchain chain) {addipcontext (getip (req); // todo needs to obtain the username addusercontext ("XXX") by yourself;} public void Init (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 .}}

Note: The current user needs to obtain the information based on the system implementation.

Configure web. xml

        <filter><filter-name>LogFilter</filter-name><filter-class>com.xiaokaceng.demo.web.controller.businesslog.LogFilter</filter-class></filter><filter-mapping><filter-name>LogFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

Create koala-businesslog.properties under the class path

Pointcut = Execution (* Org. openkoala. example. application. impl. *. *(..)) # log switch kaola. businesslog. enable = true # log export tool businesslogexporter = org. openkoala. businesslog. utils. businesslogexporterimpl # Database setting 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 # thread pool configuration # Core Thread Count log. threadpool. corepoolsize = 100 # maximum number of threads log. threadpool. maxpoolsize = 3000 # maximum queue length log. threadpool. queuecapacity = 2000 # the idle time log allowed by the thread pool maintenance thread. threadpool. keepaliveseconds = 300 # The processing policy log of the thread pool to reject tasks (available in wireless. threadpool. rejectedexecutionhandler = Java. util. concurrent. threadpoolexecutor $ callerrunspolicy

Pointcut: Business logs are recorded through the cut surface.

Businesslogexporter (Business Log output): Specify the output method. The default output is recorded in the database, and the businesslogexporter interface can be extended for custom output.

Integrate business functions

For example, if an interface implementation class is personinfoapplicationimpl. Java, You need to record the service logs for the newly added or deleted methods. The Code is as follows:

       @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 });}

Add the @ methodalias annotation to the method of the Business Log to be recorded. The value must be unique and the naming rules must comply with the Java method naming rules.

• Create the businesslogconfig folder under the class path

Groovy files used to store business logs

• Create a groovy file in the businesslogconfig folder

The file name can be arbitrary, as long as it complies with the Java class naming rules. For example, personinfoapplicationimpl. Groovy

Package VM. other. businesslog_resources.businesslogconfigclass personinfoapplicationimpl {def context def save () {"$ {getpretemplate ()}: Create personal information, name: $ {context. _ param0.name} "} def remove () {" $ {getpretemplate ()}: delete personal information "} def getpretemplate () {" $ {context. _ User }-"}}

The method name must correspond to the value of @ methodalias one by one.

• Introduce spring Configuration

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

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

• Add packagestoscan

<Value> org. openkoala. businesslog. Model </value>
