无法自动连接 activiti RuntimeService
could not auto wire activiti RuntimeService
我正在学习通过 spring 引导使用 activiti
但是我遇到了一些错误,并且使用 spring boot 和 java
搜索了太多关于 acitiviti 稳定版的信息
我正在使用 java 8 和 tomcat 8.0.3
我换了那么多版本的spring和jdk,查了那么多样本也没发现什么问题
我只有一个控制器 class 和 spring main class
当我 运行 项目出现此错误时:
Error creating bean with name 'runtimeServiceBean' defined in class path resource [org/activiti/spring/boot/JpaProcessEngineAutoConfiguration$JpaConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.activiti.engine.ProcessEngine]: : Error creating bean with name 'processEngine'defined in class path resource [org/activiti/spring/boot/JpaProcessEngineAutoConfiguration$JpaConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.activiti.spring.SpringProcessEngineConfiguration]
这是我的 RestController,除了自动装配什么都不做
import org.activiti.engine.RuntimeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MyRestController {
@Autowired
private RuntimeService runtimeService;
}
这是我的 pom.xml:

经过这么多搜索,我意识到 spring boot 2 与 activiti 有问题,然后我将 spring boot 更改为版本 1.5
然后我收到新错误:

以及新错误的原因:我在 src/main/resources/processes/
中没有任何进程
设置一些进程并删除目标文件夹
对我有用!
如果您想将 Activiti 与 Spring Boot 2.x 一起使用,我们建议您使用可在此处找到的新版 Activiti Core 7:https://search.maven.org/artifact/org.activiti/activiti-spring-boot-starter/7.0.0.SR1/jar
您可以在此处找到示例:
https://github.com/activiti/activiti-examples
使用Spring Boot 2.x你必须添加上面的依赖,并删除另一个。`
