JBPM

JBPM Spring Hibernate Bean Web

今天尝试整合Spring和JBPM，搞了一上午都没结果。每次都是SessionFactory创建失败，主要是在加载Hibernate的映射文件时出现问题，详细步骤如下：

1、修改web.xml 增加如下：

xml 代码

<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>
/WEB-INF/workflowApplicationContext.xml
param-value>
context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
listener-class>
listener>

2、在WEB-INF目录下增加Spring的配置文件workflowApplicationContext.xml.如下：

xml 代码

xml version="1.0" encoding="UTF-8"?>
>
<beans default-autowire="no" default-lazy-init="false"
default-dependency-check="none">
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>net.sourceforge.jtds.jdbc.Drivervalue>
property>
<property name="url">
<value>jdbc:jtds:sqlserver://localhost:1433/jbpm3_2value>
property>
<property name="username">
<value>savalue>
property>
<property name="password">
<value>savalue>
property>
bean>
<bean id="workflowsessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource" />
property>
<property name="mappingJarLocations">
<list>
<value>WEB-INF/lib/jbpm-jpdl.jarvalue>
<value>WEB-INF/lib/jbpm-identity.jarvalue>
list>
property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
prop>
<prop key="hibernate.show_sql">trueprop>
<prop key="hibernate.cache.provider_class">
org.hibernate.cache.HashtableCacheProvider
prop>
<prop key="hibernate.query.factory_class">
org.hibernate.hql.classic.ClassicQueryTranslatorFactory
prop>
props>
property>
bean>
beans>

3、启动Tomcat，异常

java 代码

严重: Exception sending context initialized event to listener instance of class
org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean wit
h name 'workflowsessionFactory' defined in ServletContext resource [/WEB-INF/wor

365)

a:1294)

查看JBPM的代码，发现出现异常的named quieries均为含update和delete的HQL语句，映射文件中（org.jbpm.db.hibernate.queries.hbm.xml）还包含其他的含select的HQL语句，并没有出现问题。

问题究竟出在哪里呢？如何解决？希望知道的老大告知一二！！！

4、关于SessionFactory查找映射文件的方式还有其他两种方式，写在这里备忘：）

xml 代码

<property name="configLocations">
<list>
<value>classpath:/hibernate.cfg.xmlvalue>
list>
property>

xml 代码

<property name="mappingLocations">
<value>classpath*:/org/jbpm/**/*.hbm.xmlvalue>
property>

终于解决了，在hibernateProperties的配置中去掉
<prop key="hibernate.query.factory_class">
org.hibernate.hql.classic.ClassicQueryTranslatorFactory
</prop>
这个配置就可以了～～～
或者改为
org.hibernate.hql.ast.ASTQueryTranslatorFactory

JbpmConfiguration jbpmConfiguration = jbpmTemplate.getJbpmConfiguration();
JbpmContext jc = jbpmConfiguration.getCurrentJbpmContext();
if (jc==null){
jc = jbpmConfiguration.createJbpmContext();
//System.out.println("[===创建====]");
}

jbpm与spring的整合，需要使用spring-module包
