篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springmvc 整合 camunda相关的知识，希望对你有一定的参考价值。
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

</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;
//
@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource)
return new DataSourceTransactionManager(dataSource);
@Bean
public 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;
@Bean
public ProcessEngineFactoryBean engineFactory(SpringProcessEngineConfiguration engineConfiguration)
ProcessEngineFactoryBean factoryBean = new ProcessEngineFactoryBean();
factoryBean.setProcessEngineConfiguration(engineConfiguration);
return factoryBean;
@Bean
public ProcessEngine processEngine(ProcessEngineFactoryBean factoryBean) throws Exception
return factoryBean.getObject();
@Bean
public RepositoryService repositoryService(ProcessEngine processEngine)
return processEngine.getRepositoryService();
@Bean
public RuntimeService runtimeService(ProcessEngine processEngine)
return processEngine.getRuntimeService();
@Bean
public TaskService taskService(ProcessEngine processEngine)
return processEngine.getTaskService();
@Bean
public HistoryService historyService(ProcessEngine processEngine)
return processEngine.getHistoryService();
@Bean
public 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。
