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("[e-mail]");
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;
}
}
