activiti集成spring boot的一个怪问题

最近想集成activti到spring boot中，上网找了一下例子，发现很简单，就开干了!

• 建立maven工程后，加入acitivti的引入

<dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-basic</artifactId> <version>6.0.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> 

启动spring boot应用，发现有问题了，报错如下

Caused by: java.io.FileNotFoundException: class path resource [processes/] cannot be resolved to URL because it does not exist at org.springframework.core.io.ClassPathResource.getURL(ClassPathResource.java:187) ~[spring-core-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.core.io.support.PathMatchingResourcePatternResolver.findPathMatchingResources(PathMatchingResourcePatternResolver.java:464) ~[spring-core-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.core.io.support.PathMatchingResourcePatternResolver.getResources(PathMatchingResourcePatternResolver.java:293) ~[spring-core-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.AbstractApplicationContext.getResources(AbstractApplicationContext.java:1293) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.GenericApplicationContext.getResources(GenericApplicationContext.java:233) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.activiti.spring.boot.AbstractProcessEngineConfiguration.discoverProcessDefinitionResources(AbstractProcessEngineConfiguration.java:79) ~[activiti-spring-boot-starter-basic-6.0.0.jar:na] at org.activiti.spring.boot.AbstractProcessEngineAutoConfiguration.baseSpringProcessEngineConfiguration(AbstractProcessEngineAutoConfiguration.java:74) ~[activiti-spring-boot-starter-basic-6.0.0.jar:na] at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration.springProcessEngineConfiguration(DataSourceProcessEngineAutoConfiguration.java:57) ~[activiti-spring-boot-starter-basic-6.0.0.jar:na] at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration$$EnhancerBySpringCGLIB$$4f170b93.CGLIB$springProcessEngineConfiguration$1(<generated>) ~[activiti-spring-boot-starter-basic-6.0.0.jar:na] at org.activiti.spring.boot.DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration$$EnhancerBySpringCGLIB$$4f170b93$$FastClassBySpringCGLIB$$d87b00aa.invoke(<generated>) ~[activiti-spring-boot-starter-basic-6.0.0.jar:na] 

怎么回事，跑不起来？
按报错，说要在class下找processes这个目录下
手动在resources下建个目录processes，再跑跑。
结果，报错依旧！
后面尝 试在那个processes目录下，放一个流程的xml文件，发现启动成功了！
查一下后台数据库表，发现自动发布了一个流程定义
后面发现加入配置即不会自动扫描该目录了

spring: activiti: check-process-definitions: false
