1.activiti中的mybaitis版本冲突 错误信息
Caused by: java.lang.NoSuchFieldError: INSTANCE
at com.baomidou.mybatisplus.MybatisMapperAnnotationBuilder.parseStatement(MybatisMapperAnnotationBuilder.java:332) ~[mybatis-plus-core-2.3.jar:?]

经查,是因为我用mybatis plus,要求用mybatis3.4.6,而activiti用的是mybatis3.4.2,两边有冲突,直接排除activitiv那个即好：
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring-boot-starter-basic</artifactId>
<version>6.0.0</version>
<exclusions>
<exclusion>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
</exclusion>
</exclusions>
</dependency>
2.activiti中的SecurityAutoConfiguration冲突启动项目中,报如下错

at java.lang.Class.getAnnotation(Class.java:3415) ~[?:1.8.0_181]
经查,是类SecurityAutoConfiguration有冲突,在启动时排除该类即可
@Slf4j
@EnableSwagger2
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class})
//@EnableAutoConfiguration 这个需要注释掉不然上边的排除操作无效
public class JeecgApplication {
public static void main(String[] args) throws UnknownHostException {
3.activiti中自动搜索流程文件的check-process-definitions问题
项目启动时报如下错误
activiti中自动搜索流程文件的check-process-definitions问题
项目启动时报如下错误
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:195) ~[spring-core-5.0.8.RELEASE.jar:5.0.8.RELEASE]
at org.springframework.core.io.support.PathMatchingResourcePatternResolver.findPathMatchingResources(PathMatchingResourceP
意思是说,在目录processes/寻找流程文件,这个只要配置一下check-process-definitions即好
spring:
activiti:
database-schema-update: true
check-process-definitions: false
