一、Flowable介绍及部署
 二、SpringBoot集成Flowable UI
三、Flowable UI跳过权限验证
 四、Flowable UI整合前后分离

一、引入Flowable UI相关依赖及springboot、mybatis

二、yml文件配置

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/flowable?autoReconnect=true&useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=CTT
    username: root
    password: root
  security:
    filter:
      dispatcher-types: REQUEST,FORWARD,ASYNC
flowable:
  #关闭定时任务JOB
  async-executor-activate: false
  common:
    app:
      idm-url: http://localhost:8080/expense/
  idm:
    app:
      admin:
        user-id: admin
        password: test
        first-name: admin
        last-name: admin
  rest:
    app:
      authentication-mode: verify-privilege
  modeler:
    app:
      rest-enabled: true
  database-schema-update: false
mybatis:
  mapper-locations: classpath:/META-INF/modeler-mybatis-mappings/*.xml
  config-location: classpath:/META-INF/mybatis-config.xml
  configuration-properties:
    prefix:
    blobType: BLOB
    boolValue: TRUE
server:
  servlet:
    context-path: /expense

三、mybatis配置

resources/META-INF/mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
	PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
	"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 配置mybatis的一些参数 -->
	<settings>
		<!-- 是否开启二级缓存 -->
		<setting name="cacheEnabled" value="false" />
		<!-- 延时加载的配置 -->
		<setting name="lazyLoadingEnabled" value="false" />
		<setting name="multipleResultSetsEnabled" value="true" />

	</settings>
</configuration>

三、两个配置类

AppDispatcherServletConfiguration

@Configuration
@ComponentScan(value = {
        "org.flowable.ui.idm.rest.app",
        "org.flowable.ui.common.rest.exception",
        "org.flowable.ui.modeler.rest.app",
        "org.flowable.ui.common.rest"},
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = RemoteAccountResource.class),
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = StencilSetResource.class),
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = EditorUsersResource.class),
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = EditorGroupsResource.class)
        })
@EnableAsync
public class AppDispatcherServletConfiguration implements WebMvcRegistrations {

    private static final Logger LOGGER = LoggerFactory.getLogger(AppDispatcherServletConfiguration.class);

    @Bean
    public SessionLocaleResolver localeResolver() {
        return new SessionLocaleResolver();
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        LOGGER.debug("Configuring localeChangeInterceptor");
        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("language");
        return localeChangeInterceptor;
    }

    @Override
    public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
        LOGGER.debug("Creating requestMappingHandlerMapping");
        RequestMappingHandlerMapping requestMappingHandlerMapping = new RequestMappingHandlerMapping();
        requestMappingHandlerMapping.setUseSuffixPatternMatch(false);
        requestMappingHandlerMapping.setRemoveSemicolonContent(false);
        Object[] interceptors = {localeChangeInterceptor()};
        requestMappingHandlerMapping.setInterceptors(interceptors);
        return requestMappingHandlerMapping;
    }

ApplicationConfiguration

@Configuration
@EnableConfigurationProperties({FlowableIdmAppProperties.class, FlowableModelerAppProperties.class})
@ComponentScan(basePackages = {
        "org.flowable.ui.idm.conf",
        "org.flowable.ui.idm.security",
        "org.flowable.ui.idm.service",
        "org.flowable.ui.modeler.repository",
        "org.flowable.ui.modeler.service",
        "org.flowable.ui.common.filter",
        "org.flowable.ui.common.service",
        "org.flowable.ui.common.repository",
        "org.flowable.ui.common.security",
        "org.flowable.ui.common.tenant"}, excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = org.flowable.ui.idm.conf.ApplicationConfiguration.class)})
public class ApplicationConfiguration {


    @Bean
    public ServletRegistrationBean apiServlet(ApplicationContext applicationContext) {
        AnnotationConfigWebApplicationContext dispatcherServletConfiguration = new AnnotationConfigWebApplicationContext();
        dispatcherServletConfiguration.setParent(applicationContext);
        dispatcherServletConfiguration.register(ApiDispatcherServletConfiguration.class);
        DispatcherServlet servlet = new DispatcherServlet(dispatcherServletConfiguration);
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(servlet, "/api/*");
        registrationBean.setName("Flowable IDM App API Servlet");
        registrationBean.setLoadOnStartup(1);
        registrationBean.setAsyncSupported(true);
        return registrationBean;
    }

@Import({
        ApplicationConfiguration.class,
        AppDispatcherServletConfiguration.class
})
@EnableTransactionManagement
@SpringBootApplication

至此，项目已基本配置完毕，可正常启动

注意：

application.yml 中flowable.database-schema-update配置：

true：数据库升级

false：检验版本

create-drop:

drop-create：

值为true时报错可改为false，只校验版本

当校验版本出现如下异常时

将这两张表中的全部版本信息改为异常中需要的版本信息

五、启动结果：

六、前端文件

问题：

此时项目已经启动，但是我们按照war包形式访问项目时，会出现如下问题：

是因为maven依赖并没有引入相关的静态资源文件

解决：

资源文件

将war包下里\WEB-INF\classes\static路径资源文件拷贝至springboot项目制resources下对应的文件夹内（如下规则）：

将以下两个文件放入resources内（流程节点）

配置

@Configuration
public class MyWebMvcConfigurerAdapter implements WebMvcConfigurer {

    //静态资源配置
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/p/**")
                .addResourceLocations("classpath:/templates/page/");
        registry.addResourceHandler("/a/**")
                .addResourceLocations("classpath:/templates/assets/");
        registry.addResourceHandler("/**")
                .addResourceLocations("classpath:/static/");
        registry.addResourceHandler("/idm/**")
                .addResourceLocations("classpath:/idm/");
    }

    //跨域配置
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedMethods("*")
                .allowedOrigins("*")
                .allowedHeaders("*")
                .allowCredentials(true);
    }

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.setAllowCredentials(true);
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");

        return corsConfiguration;
    }


    /**
     * 跨域过滤器
     *
     * @return
     */
    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig()); 
        return new CorsFilter(source);
    }
}
