springmvc 整合 camunda

SpringMVC 整合
2023-09-11 14:21:21 时间

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

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。
