**1. 請先準備好如下環境** JDK1.8+、MySQL5+、IntelliJ IDEA或者Eclipse。 **2. IDEA中安裝Activiti流程設計器** :-:  如果IDEA中找不到 actiBPM 插件，可以如下安裝： （1）下載actiBPM的JAR包。 地址：[https://plugins.jetbrains.com/](https://plugins.jetbrains.com/)   （2）在IDEA中選擇從磁盤中導入該JAR包，選擇下載的actibpm.jar包。  （3）重啟IDEA即可。 **3. 創建一個maven項目，`pom.xml`如下** ```xml <!-- activiti 的相關包 mysql的驅動包 mybatis log4j 數據庫鏈接池--> <properties> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <activiti.version>7.0.0.Beta1</activiti.version> </properties> <dependencies> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>${activiti.version}</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>${activiti.version}</version> </dependency> <!-- bpmn 模型處理 --> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-model</artifactId> <version>${activiti.version}</version> </dependency> <!-- bpmn 轉換 --> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-converter</artifactId> <version>${activiti.version}</version> </dependency> <!-- bpmn json數據轉換 --> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-json-converter</artifactId> <version>${activiti.version}</version> </dependency> <!-- bpmn 布局 --> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-layout</artifactId> <version>${activiti.version}</version> </dependency> <!-- activiti 云支持 --> <dependency> <groupId>org.activiti.cloud</groupId> <artifactId>activiti-cloud-services-api</artifactId> <version>${activiti.version}</version> </dependency> <!-- mysql驅動 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.40</version> </dependency> <!-- mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.5</version> </dependency> <!-- 鏈接池 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.6</version> </dependency> </dependencies> ``` **4. log4j日志配置文件`resources/log4j.properties`** ```properties # Set root category priority to INFO and its only appender to CONSOLE. #log4j.rootCategory=INFO, CONSOLE debug info warn error fatal log4j.rootCategory=debug, CONSOLE, LOGFILE # Set the enterprise logger category to FATAL and its only appender to CONSOLE. log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE # CONSOLE is set to be a ConsoleAppender using a PatternLayout. log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r[%15.15t] %-5p %30.30c %x -
