2. FlowableConfig配置類

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;

/**
 * 說明：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("宋體");
        engineConfiguration.setLabelFontName("宋體");
        engineConfiguration.setAnnotationFontName("宋體");
    }
    
}

3.重寫 SecurityUtils 重構流程編輯器獲取用戶信息

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;

/**
 * 說明：重構流程編輯器獲取用戶信息
 * 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("[email protected]");
		user.setPassword("123456");
		List<String> pris = new ArrayList<>();
		pris.add(DefaultPrivileges.ACCESS_MODELER);
		pris.add(DefaultPrivileges.ACCESS_IDM);
		pris.add(DefaultPrivileges.ACCESS_ADMIN);

		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;
	}
}
