If you use depends on the latest activiti-spring-boot-starter 7.1.0.M5 version , start the error:
Parameter 0 of method userGroupManager in org.activiti.core.common.spring.identity.config.ActivitiSpringIdentityAutoConfiguration required a bean of type 'org.springframework.security.core.userdetails.UserDetailsService' that could not be found.
The following candidates were found but could not be injected:
- Bean method 'inMemoryUserDetailsManager' in 'UserDetailsServiceAutoConfiguration' not loaded because @ConditionalOnBean did not find required type 'org.springframework.security.config.annotation.ObjectPostProcessor'
Because of SpringSecurity according Two Internet troubleshooting configuration
@SpringBootApplication(exclude = {
SecurityAutoConfiguration.class, ManagementWebSecurityAutoConfiguration.class
})
public class SpringbootAcitvitiApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootAcitvitiApplication.class, args);
}
}This method is ineffective, however, there is a SecurityAutoConfiguration.class with activiti package, but this version of the jar package does not have this class.
