Spring boot 整合Activiti中遇到的问题

 Pom.xml 配置<!-- activiti  -->
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring-boot-starter-basic</artifactId>
<version>6.0.0</version>
</dependency>

<!-- mysql 驱动 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency>

#连接信息application.properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/jt?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
spring.activiti.check-process-definitions: false

SpringBoot启动

启动报错
1、org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.activiti.spring.boot.SecurityAutoConfiguration‘: Initialization of bean failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy；
2、org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘requestMappingHandlerMapping‘ defined in class path resource 
解决办法：启动类上加上 @SpringBootApplication(exclude = SecurityAutoConfiguration.class)即可；因为activiti-spring-boot-starter-basic中引用了spring-boot-starter-security

No.2
启动报错
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘springProcessEngineConfiguration‘ defined in class path resource [xxxxx/xxxx/xxx.java]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.activiti.spring.SpringProcessEngineConfiguration]: Factory method ‘springProcessEngineConfiguration‘ threw exception; nested exception is java.io.FileNotFoundException: class path resource [processes/] cannot be resolved to URL because it does not exist；

意思是在resource下没有找到processes文件夹；

解决办法：在resource目录下添加processes文件夹，并且文件夹不能为空 或是在application.properties文件中加上如下配置（注意是spring节点下）
activiti:
    database-schema-update: true
    # 自动部署验证设置:true-开启（默认）、false-关闭
    check-process-definitions: false;

No.3

启动报错

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘runtimeServiceBean‘ defined in class path resource [com/example/config/ActivitiConfig.class]: Unsatisfied dependency expressed through method ‘runtimeServiceBean‘ parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘processEngine‘: FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName.

解决办法：配置数据源时url前加上jdbc-；如：jdbc-url: jdbc:mysql://localhost:3306/activity?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
