最近集成activi 6集成到spring boot中,遇到一些问题,记录一二.

• activiti中的mybaitis版本冲突
  集成activit6需引入如下配置

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

但项目启动报如下错误

Caused by: java.lang.NoSuchFieldError: INSTANCE
    at com.baomidou.mybatisplus.MybatisMapperAnnotationBuilder.parseStatement(MybatisMapperAnnotationBuilder.java:332) ~[mybatis-plus-core-2.3.jar:?]
    at com.baomidou.mybatisplus.MybatisMapperAnnotationBuilder.parse(MybatisMapperAnnotationBuilder.java:153) ~[mybatis-plus-core-2.3.jar:?]
    at com.baomidou.mybatisplus.MybatisMapperRegistry.addMapper(MybatisMapperRegistry.java:86) ~[mybatis-plus-core-2.3.jar:?]
    at com.baomidou.mybatisplus.MybatisConfiguration.addMapper(MybatisConfiguration.java:101) ~[mybatis-plus-core-2.3.jar:?]
    at org.apache.ibatis.builder.xml.XMLMapperBuilder.bindMapperForNamespace(XMLMapperBuilder.java:408) ~[mybatis-3.4.2.jar:3.4.2]
    at org.apache.ibatis.builder.xml.XMLMapperBuilder.parse(XMLMapperBuilder.java:94) ~[mybatis-3.4.2.jar:3.4.2]
    at com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean.buildSqlSessionFactory(MybatisSqlSessionFactoryBean.java:583) ~[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>

• activiti中的SecurityAutoConfiguration冲突
  启动项目中,报如下错

    at sun.reflect.annotation.AnnotationParser.parseClassArray(AnnotationParser.java:724) ~[?:1.8.0_181]

经查,是类SecurityAutoConfiguration有冲突,在启动时排除该类即可

@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
public class StarmarkApplication {

    public static void main(String[] args) {
        SpringApplication.run(StarmarkApplication.class, args);
    }

}

• 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(PathMatchingResourcePatternResolver.java:495) ~[spring-core-5.0.8.RELEASE.jar:5.0.8.RELEASE]

    at org.springframework.context.support.GenericApplicationContext.getResources(GenericApplicationContext.java:233) ~[spring-context-5.0.8.RELEASE.jar:5.0.8.RELEASE]

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

  activiti:
      database-schema-update: true
      check-process-definitions: false

至此,activiti6集成的问题记录完毕!
