2. FlowableConfig配置类

package org.fh.config;
    
    import org.flowable.spring.SpringProcessEngineConfiguration;
    import org.flowable.spring.boot.EngineConfigurationConfigurer;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.stereotype.Controller;
    
    /**
     * 说明：Flowable配置
     * 作者：FH Admin
     * from：fhadmin.cn
     */
    @Controller
    @Configuration
    public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
    	
        @Override
        public void configure(SpringProcessEngineConfiguration engineConfiguration) {
            engineConfiguration.setActivityFontName("宋体");
            engineConfiguration.setLabelFontName("宋体");
            engineConfiguration.setAnnotationFontName("宋体");
        }
        
    }

3.重写 SecurityUtils 重构流程编辑器获取用户信息

package org.flowable.ui.common.security;
    
    import org.fh.util.Jurisdiction;
    import org.flowable.common.engine.api.FlowableIllegalStateException;
    import org.flowable.idm.api.User;
    import org.flowable.ui.common.model.RemoteUser;
    import org.springframework.security.core.Authentication;
    import org.springframework.security.core.context.SecurityContext;
    import org.springframework.security.core.context.SecurityContextHolder;
    
    import java.util.ArrayList;
    import java.util.List;
    
    /**
     * 说明：重构流程编辑器获取用户信息
     * 作者：FH Admin
     * from：fhadmin.cn
     */
    public class SecurityUtils {
    
    	private static User assumeUser;
    	
    	private static SecurityScopeProvider securityScopeProvider = new FlowableSecurityScopeProvider();
    
    	private SecurityUtils() {
    	}
    
    	/**
    	 * Get the login of the current user.
    	 */
    	public static String getCurrentUserId() {
    		User user = getCurrentUserObject();
    		if (user != null) {
    			return user.getId();
    		}
    		return null;
    	}
    
    	/**
    	 * @return the {@link User} object associated with the current logged in user.
    	 */
    	public static User getCurrentUserObject() {
    		if (assumeUser != null) {
    			return assumeUser;
    		}
    
    		RemoteUser user = new RemoteUser();
    		user.setId(Jurisdiction.getUsername());
    		user.setDisplayName(Jurisdiction.getName());
    		user.setFirstName(Jurisdiction.getName());
    		user.setLastName(Jurisdiction.getName());
    		user.setEmail("admin@flowable.com");
    		user.setPassword("123456");
    		List<String> pris = new ArrayList<>();
    		pris.add(DefaultPrivileges.ACCESS_MODELER);
    		pris.add(DefaultPrivileges.ACCESS_IDM);
    		pris.add(DefaultPrivileges.ACCESS_ADMIN);
    		pris.add(DefaultPrivileges.ACCESS_TASK);
    		pris.add(DefaultPrivileges.ACCESS_REST_API);
    		user.setPrivileges(pris);
    		return user;
    	}
    	
        public static void setSecurityScopeProvider(SecurityScopeProvider securityScopeProvider) {
            SecurityUtils.securityScopeProvider = securityScopeProvider;
        }
    
        public static SecurityScope getCurrentSecurityScope() {
            SecurityContext securityContext = SecurityContextHolder.getContext();
            if (securityContext != null && securityContext.getAuthentication() != null) {
                return getSecurityScope(securityContext.getAuthentication());
            }
            return null;
        }
    
        public static SecurityScope getSecurityScope(Authentication authentication) {
            return securityScopeProvider.getSecurityScope(authentication);
        }
    
        public static SecurityScope getAuthenticatedSecurityScope() {
            SecurityScope currentSecurityScope = getCurrentSecurityScope();
            if (currentSecurityScope != null) {
                return currentSecurityScope;
            }
            throw new FlowableIllegalStateException("User is not authenticated");
        }
    
    	public static void assumeUser(User user) {
    		assumeUser = user;
    	}
    
    	public static void clearAssumeUser() {
    		assumeUser = null;
    	}
    }
