JBPM（四）—SSH框架整合JBPM详解编程语言

• 编程笔记

jar包引入
如果没有使用maven，为防止jar包冲突，需要将JBPM中多余的jar包删除，如：
cglib.jar
commons-collections.jar
commons-logging.jar
freemarker.jar
hibernate-core.jar
hsqldb.jar
javassist.jar
jta.jar
junit.jar
log4j.jar
mail.jar
mysql-connector-java.jar
等。

如果使用maven坐标导入jar包
pom坐标：

<repositories> 
        <!--JBPM依赖包 maven2资源库 --> 
        <repository> 
            <id>Jboss-JBPM-Repositories</id> 
            <name>JbossJBPM</name> 
            <url>https://repository.jboss.org/nexus/content/repositories/releases</url> 
        </repository> 
</repositories> 
 
<!--JBPM4.4 --> 
        <dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-api</artifactId> 
            <version>4.4</version> 
        </dependency> 
        <dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-jpdl</artifactId> 
            <version>4.4</version> 
        </dependency> 
        <dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-pvm</artifactId> 
            <version>4.4</version> 
        </dependency> 
        <dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-log</artifactId> 
            <version>4.4</version> 
        </dependency> 
        <dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-bpmn</artifactId> 
            <version>4.4</version> 
        </dependency>

配置文件整合

将JBPM解压目录下examples/src/jbpm.cfg.xml 复制到resources
用<import resource=”jbpm.tx.spring.cfg.xml” />替换掉jbpm.cfg.xml 文件中的
<import resource=”jbpm.tx.hibernate.cfg.xml” />

建立JBPM18张表，在spring配置文件 applicationContext-common.xml 引入 hbm 

<!-- 引入 jbpm 配置文件  --> 
        <property name="mappingResources"> 
            <list> 
                <value>jbpm.repository.hbm.xml</value> 
                <value>jbpm.execution.hbm.xml</value> 
                <value>jbpm.history.hbm.xml</value> 
                <value>jbpm.task.hbm.xml</value> 
                <value>jbpm.identity.hbm.xml</value> 
            </list> 
        </property>

修改 mysql方言 ： org.hibernate.dialect.MySQL5InnoDBDialect

在spring配置文件中配置processEngine

<!-- jbpm提供工具类，获得流程引擎 --> 
    <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper"> 
      <property name="jbpmCfg" value="jbpm.cfg.xml"></property> 
    </bean> 
 
    <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />

整合常见错误：
1.发布流程时报Caused by: java.lang.ClassNotFoundException:
javax.mail.Message$RecipientType
解决方式：JBPM 运行，需要依赖 javamail的 jar 包

        <!-- javamail --> 
        <dependency> 
            <groupId>javax.mail</groupId> 
            <artifactId>mail</artifactId> 
            <version>1.4</version> 
        </dependency>

2.将JBPM整合后项目，在tomcat运行起来报javax.servlet.ServletException: java.lang.LinkageError: loader constraint violation: when resolving interface method “javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;” the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/index_jsp, and the class loader (instance of org/codehaus/plexus/classworlds/realm/ClassRealm) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature

原因： jar包冲突
Juel-api.jar 和 tomcat中el-api.jar 冲突

如果是外部Tomcat，解决方法： 将juel三个jar包放入tomcat /lib 下替换 el-api.jar
删除原来项目中 juel三个jar 包

使用maven内置Tomcat，解决方法：
将工程内部 juel三个jar 包 设置 provided 

<dependencyManagement> 
    <dependencies> 
        <dependency> 
            <groupId>juel</groupId> 
            <artifactId>juel-api</artifactId> 
            <version>2.2.1</version> 
            <scope>provided</scope> 
        </dependency> 
        <dependency> 
            <groupId>juel</groupId> 
            <artifactId>juel-impl</artifactId>

            <scope>provided</scope> 
        </dependency> 
        <dependency>

            <scope>provided</scope> 
        </dependency> 
    </dependencies>

在内置tomcat中 引入juel的jar 包

                <!-- 引入juel的jar包 --> 
                <dependencies> 
                    <dependency> 
                        <groupId>de.odysseus.juel</groupId> 
                        <artifactId>juel-api</artifactId> 
                        <version>2.2.6</version> 
                    </dependency> 
                    <dependency> 
                        <groupId>de.odysseus.juel</groupId> 
                        <artifactId>juel-impl</artifactId> 
                        <version>2.2.6</version> 
                    </dependency> 
                </dependencies>

3.slf4j 日志冲突错误 ,slf4j-log4j 和 slf4j-jdk 冲突

<dependency> 
            <groupId>org.jbpm.jbpm4</groupId> 
            <artifactId>jbpm-pvm</artifactId> 
            <version>4.4</version>

                </exclusion> 
            </exclusions>
