springmvc 整合 camunda
2024-04-23 09:53:18
参考官网：Process Engine 配置 | docs.camunda.org
一 POM
注意：
1 低版本c3p0会报错：Method com/mchange/v2/c3p0/impl/NewProxyResultSet.isClosed()Z
千万记得要删除Target包下的旧版本！！！ <dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.4</version> </dependency>2 低版本jackson会报错：com.fasterxml.jackson.databind.exc.InvalidDefinitionException
<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.8</version> </dependency>3 如果先前创建过Camunda会报错：HistoryLevel mismatch
删除Camunda，重新创建
4 springmvc4 中 web.xml配置的Log4jConfigListener
在springmvc5中已经弃用，所以需要修改
参考：spring5.0解决Log4jConfigListener过期问题_dabaishaflyw的博客-CSDN博客

二 web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"><display-name>webApprove</display-name><description>审批系统</description><context-param><param-name>webAppRootKey</param-name><param-value>webApprove.root</param-value></context-param><context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j/log4j.properties</param-value></context-param><context-param><param-name>log4jRefreshInterval</param-name><param-value>6000</param-value></context-param><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/applicationContext.xml</param-value></context-param><!-- log4j2-begin --><listener><listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class></listener><filter><filter-name>log4jServletFilter</filter-name><filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class></filter><filter-mapping><filter-name>log4jServletFilter</filter-name><url-pattern>/*</url-pattern><dispatcher>REQUEST</dispatcher><dispatcher>FORWARD</dispatcher><dispatcher>INCLUDE</dispatcher><dispatcher>ERROR</dispatcher></filter-mapping><!-- log4j2-end --><listener><description>spring监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><description>防止内存泄露</description><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><listener><listener-class>org.springframework.web.context.request.RequestContextListener</listener-class></listener><filter><filter-name>springSessionRepositoryFilter</filter-name><filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class></filter><filter-mapping><filter-name>springSessionRepositoryFilter</filter-name><url-pattern>/*</url-pattern><dispatcher>REQUEST</dispatcher><dispatcher>ERROR</dispatcher></filter-mapping><filter><filter-name>characterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter><filter-name>setBasePathFilter</filter-name><filter-class>com.abc.web.filter.SetBasePathFilter</filter-class></filter><filter-mapping><filter-name>setBasePathFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter><filter-name>checkSessionFilter</filter-name><filter-class>com.abc.web.filter.CheckSessionFilter</filter-class><init-param><param-name>excludeUrl</param-name><param-value>.*(login|check|setCookie).do.*</param-value></init-param></filter><filter-mapping><filter-name>checkSessionFilter</filter-name><url-pattern>*.do</url-pattern></filter-mapping><filter><filter-name>hibernateFilter</filter-name><filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class><!-- <init-param><param-name>excludeSuffixs</param-name><param-value>js,css,jpg,gif</param-value></init-param><init-param><param-name>singleSession</param-name><param-value>true</param-value></init-param> --><init-param><param-name>sessionFactoryBeanName</param-name><param-value>sessionFactory</param-value></init-param></filter><filter-mapping><filter-name>hibernateFilter</filter-name><url-pattern>*.do</url-pattern></filter-mapping><servlet><servlet-name>webApprove</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/springmvc-servlet.xml</param-value></init-param><init-param><param-name>detectAllHandlerExceptionResolvers</param-name><param-value>false</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>webApprove</servlet-name><url-pattern>/</url-pattern></servlet-mapping><session-config><session-timeout>120</session-timeout><tracking-mode>COOKIE</tracking-mode></session-config><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list>
</web-app>三 官网中配置了：
但我的datasource已经在application.xml中配置了。
所以此处注释了
package com.abc.webApprove.config;import org.camunda.bpm.engine.*;
import org.camunda.bpm.engine.spring.ProcessEngineFactoryBean;
import org.camunda.bpm.engine.spring.SpringProcessEngineConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.transaction.PlatformTransactionManager;import javax.sql.DataSource;@Configuration
public class LoanApplicationContext {
// @Bean
// public DataSource dataSource() {
// DriverManagerDataSource dataSource = new DriverManagerDataSource();
// dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
// dataSource.setUrl("jdbc:mysql://ip/abc_camunda?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&autoReconnectForPools=true&noAccessToProcedureBodies=true\n");
// dataSource.setUsername(" ");
// dataSource.setPassword(" ");
// return dataSource;
// }@Beanpublic PlatformTransactionManager transactionManager(DataSource dataSource) {return new DataSourceTransactionManager(dataSource);}@Beanpublic SpringProcessEngineConfiguration engineConfiguration(DataSource dataSource, PlatformTransactionManager transactionManager) {SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();configuration.setProcessEngineName("engine");configuration.setDataSource(dataSource);configuration.setTransactionManager(transactionManager);configuration.setDatabaseSchemaUpdate("true");configuration.setJobExecutorActivate(false);return configuration;}@Beanpublic ProcessEngineFactoryBean engineFactory(SpringProcessEngineConfiguration engineConfiguration) {ProcessEngineFactoryBean factoryBean = new ProcessEngineFactoryBean();factoryBean.setProcessEngineConfiguration(engineConfiguration);return factoryBean;}@Beanpublic ProcessEngine processEngine(ProcessEngineFactoryBean factoryBean) throws Exception {return factoryBean.getObject();}@Beanpublic RepositoryService repositoryService(ProcessEngine processEngine) {return processEngine.getRepositoryService();}@Beanpublic RuntimeService runtimeService(ProcessEngine processEngine) {return processEngine.getRuntimeService();}@Beanpublic TaskService taskService(ProcessEngine processEngine) {return processEngine.getTaskService();}@Beanpublic HistoryService historyService(ProcessEngine processEngine) {return processEngine.getHistoryService();}@Beanpublic ManagementService managementService(ProcessEngine processEngine) {return processEngine.getManagementService();}
}
四 测试参考官网
因为bpmn文件发送比较麻烦，所以这里就不演示了。
