activiti学习1:开发环境的搭建

本文中使用maven+eclipse搭建activiti-5.14的开发环境

一、创建maven工程

创建一个普通的java工程,pom文件的内容如下

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.lyy</groupId>
    <artifactId>activtiviti-study-01</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-engine</artifactId>
            <version>5.14</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.26</version>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>

        <dependency>
            <groupId>c3p0</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.1.2</version>
            <type>jar</type>
            <scope>compile</scope>
        </dependency>
    </dependencies>
</project>

二、添加activiti的配置文件

在工程的resources目录下创建activiti的配置文件,名称为activiti.cfg.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

    <!-- 配置使用默认bean名称的流程引擎配置对象 -->
    <bean id="processEngineConfiguration"
        class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        <property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti_01"></property>
        <property name="jdbcUsername" value="root"></property>
        <property name="jdbcPassword" value="root"></property>
        <property name="databaseSchemaUpdate" value="true"></property>
    </bean>

</beans>

三、测试

新建一个测试类，添加如下代码，

public class Test1 {
    
    /**
     * 测试环境是否可用
     */
    @Test
    public void test1() {
    ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResourceDefault();
    System.out.println(configuration);
    }

}

运行测试方法test1，如果正常执行，并输出ProcessEngineConfiguration对象的地址，则表示开发环境搭建成功。

四、总结

用maven搭建activiti的开发环境，需要先引入activiti的依赖

<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-engine</artifactId>
    <version>5.14</version>
</dependency>

因为要操作数据库，所以需要引入msql的驱动和数据库连接池

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.26</version>
</dependency>
<dependency>
    <groupId>c3p0</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.1.2</version>
    <type>jar</type>
    <scope>compile</scope>
</dependency>
