Question

我正在学习在弹簧靴上使用activiti 但是我遇到了一些错误，并且使用Spring Boot和Java搜寻了有关Acitiviti稳定版本的太多信息

我正在使用Java 8和tomcat 8.0.3

我更改了spring和jdk的这么多版本，并检查了那么多示例，但找不到任何问题我只有控制器班和春季班当我运行项目时出现此错误：

 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，除了自动接线外什么也不做

       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：

Answer 1

如果您想将Activiti与Spring Boot 2.x一起使用，我们建议使用Activiti Core 7的新版本，可以在这里找到：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

Answer 2

经过如此多的搜索，我意识到Spring Boot 2的Activiti有问题，然后我将Spring Boot更改为1.5版然后我得到新的错误：

ControlTemplate

以及新错误的原因：我在src / main / resources / processes /中没有任何进程

设置一些过程并删除目标文件夹

对我有用！

Answer 3

使用Spring Boot 2.x，您必须在上面添加依赖项，并删除另一个依赖项。

   <dependency>
        <groupId>org.activiti</groupId>
        <artifactId>activiti-spring-boot-starter</artifactId>
        <version>7.0.0.SR1</version>
    </dependency>`
