jfinal-dreampie

jfinal-dreampie 是一个基于jfinal的开源框架库，主要集成或调优功能如下:

1.缓存维护更细粒度

 @CacheNameRemove(name = AppConstants.DEFAULT_CACHENAME)


@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
public @interface CacheNameRemove {
  String name();

  String[] keys() default {};
}

//根据key值来移除基于某个特定方法的缓存，而不是移除整个controller下的缓存

String controllerKey = ai.getControllerKey();
    if (!ValidateUtils.me().isNullOrEmpty(removeCacheName)) {
      String keyPrefix = null;
      if (!ValidateUtils.me().isNullOrEmpty(removeCacheKeys)) {
        for (String removeKey : removeCacheKeys) {
          keyPrefix = controllerKey + SLASH + removeKey;
          removeByCacheKey(removeCacheName, keyPrefix);
        }
      } else {
        keyPrefix = controllerKey;
        removeByCacheKey(removeCacheName, keyPrefix);
      }
    }

2.增加Slf4jLogger实现，然日志配置能基于任何Slf4j下的log实现，如logback

public class Slf4jLogFactory implements ILoggerFactory

3.基础model实现，实现基础的常用的部分功能用于复用

 public List<M> findAll() {
    return find(getSelectSql() + getExceptSelectSql());
  }

  public List<M> findBy(String where, Object... paras) {
    return find(getSelectSql() + getExceptSelectSql() + getWhere(where), paras);
  }

  public List<M> findTopBy(int topNumber, String where, Object... paras) {
    return paginate(1, topNumber, getSelectSql(), getExceptSelectSql() + getWhere(where), paras).getList();
  }

  public M findFirstBy(String where, Object... paras) {
    return findFirst(getSelectSql() + getExceptSelectSql() + getWhere(where), paras);
  }

  public Page<M> paginateAll(int pageNumber, int pageSize) {
    return paginate(pageNumber, pageSize, getSelectSql(), getExceptSelectSql());
  }

  public Page<M> paginateBy(int pageNumber, int pageSize, String where, Object... paras) {
    return paginate(pageNumber, pageSize, getSelectSql(), getExceptSelectSql() + getWhere(where), paras);
  }

  public boolean updateAll(String set, Object... paras) {
    return Db.update(getUpdateSql() + getSet(set), paras) > 0;
  }

  public boolean updateBy(String set, String where, Object... paras) {
    return Db.update(getUpdateSql() + getSet(set) + getWhere(where), paras) > 0;
  }

  public boolean deleteAll() {
    return Db.update(getDeleteSql()) > 0;
  }

  public boolean deleteBy(String where, Object... paras) {
    return Db.update(getDeleteSql() + getWhere(where), paras) > 0;
  }

  public boolean dropAll() {
    return Db.update(getDropSql()) > 0;
  }

  public boolean dropBy(String where, Object... paras) {
    return Db.update(getDropSql() + getWhere(where), paras) > 0;
  }

4.akka异步执行框架

public class AkkaPlugin implements IPlugin


Akka.system().scheduler().scheduleOnce(Duration.create(1000, TimeUnit.MILLISECONDS),
        new Runnable() {
          @Override
          public void run() {
            //do Something
          }
        }, Akka.system().dispatcher());

5.atmosphere  chat demo

@ManagedService(path = "/im/{room: [a-zA-Z][a-zA-Z_0-9]*}")
public class ChatRoom {
}

6.coffeescript  compiler plugin,编译coffeescript代码，并监控文件改动重新编译

public class CoffeeScriptPlugin implements IPlugin {
}

7.Flyway 数据库自动脚本升级 Plugin，用于自动生成或升级数据库，避免不断使用数据库工具修改数据导致的版本问题

public class FlywayPlugin implements IPlugin {
}

8.lesscss compiler plugin，编译less代码，并监控文件改动重新编译

public class LessCssPlugin implements IPlugin {
}

9.mailer 邮件发送plugin，使用akka异步发送邮件

 Akka.system().scheduler().scheduleOnce(Duration.create(1000, TimeUnit.MILLISECONDS),
        new Runnable() {
          @Override
          public void run() {
            MailerConf mailerConf = MailerPlugin.mailerConf;
            HtmlEmail htmlEmail = new HtmlEmail();
            htmlEmail.setCharset(mailerConf.getCharset());
            htmlEmail.setSocketTimeout(mailerConf.getTimeout());
            htmlEmail.setCharset(mailerConf.getEncode());
            htmlEmail.setHostName(mailerConf.getHost());
            if (!ValidateUtils.me().isNullOrEmpty(mailerConf.getSslport()))
              htmlEmail.setSslSmtpPort(mailerConf.getSslport());
            if (!ValidateUtils.me().isNullOrEmpty(mailerConf.getPort()))
              htmlEmail.setSmtpPort(Integer.parseInt(mailerConf.getPort()));
            htmlEmail.setSSLOnConnect(mailerConf.isSsl());
            htmlEmail.setStartTLSEnabled(mailerConf.isTls());
            htmlEmail.setDebug(mailerConf.isDebug());
            htmlEmail.setAuthenticator(new DefaultAuthenticator(mailerConf.getUser(), mailerConf.getPassword()));
            try {
              htmlEmail.setFrom(mailerConf.getFrom(), mailerConf.getName());
              htmlEmail.setSubject(subject);
              htmlEmail.addTo(recipients);
              htmlEmail.setHtmlMsg(body);
              // set the alternative message
              htmlEmail.setTextMsg("Your email client does not support HTML messages");
              if (!ValidateUtils.me().isNullOrEmpty(attachment))
                htmlEmail.attach(attachment);
              htmlEmail.send();
            } catch (EmailException e) {
              e.printStackTrace();
            }
          }
        }, Akka.system().dispatcher());

10.自定义验证码，可以自定义使用字符或者数字，颜色和样式可以自调

public class PatchcaRender extends Render {
  private static final String CODE_CHAR = "0123456789";
}

11.QuartzPlugin使用quartz执行定时任务，参照部分网络实例，简易实现

QuartzFactory.me().startJobOnce(TimeUtils.me().toString(DateTime.now()), ++jobId, "stati", this.getClass().getSimpleName(), OrderDataJob.class, param);

12.shiro权限框架，基于数据库url配置过滤，验证码验证

//读取数据库权限只需实现该接口
public interface JdbcAuthzService {
  public Map<String, AuthzHandler> getJdbcAuthz();
}

13.shiro的freemarker标签库

<@shiro.hasPermission name="P_USER">
                <li><a href="/admin/user">${i18n.getText("admin.user")}</a></li>
            </@shiro.hasPermission>

14.xss过滤的StringEscapeUtils过滤器实现

public class AttackHandler extends Handler {
  @Override
  public void handle(String target, HttpServletRequest request, HttpServletResponse response, boolean[] isHandled) {
    request = new HttpServletRequestWrapper(request);
    nextHandler.handle(target, request, response, isHandled);
  }
}

15.json数据请求时，返回的error信息使用json字符串

public class JsonErrorRenderFactory implements IErrorRenderFactory {
  public Render getRender(int errorCode, String view) {
    if (ThreadLocalUtil.isJson())
      return new JsonErrorRender(errorCode, view);
    else
      return new ErrorRender(errorCode, view);
  }
}

16.自动绑定多数据源的tablebind

AutoMultiSourceTableBindPlugin tableBindDefault = new AutoMultiSourceTableBindPlugin(druidDefault, SimpleNameStyles.LOWER);
//让default数据源排除shop目录下的model，因为该目录的model属于custom数据源
tableBindDefault.addExcludePaths("cn.dreampie.function.shop");

 AutoMultiSourceTableBindPlugin tableBindCustom = new AutoMultiSourceTableBindPlugin(druidCustom, SimpleNameStyles.LOWER);
//让custom只扫描shop目录，注意当使用includepaths是只会扫描配置的路径，如果没有使用includepaths会扫描全路径
tableBindCustom.addIncludePaths("cn.dreampie.function.shop");

17.压缩请求数据的gzipFilter，可测试

<!--gzip compress filter-->
  <filter>
    <filter-name>gzipFilter</filter-name>
    <filter-class>cn.dreampie.common.web.filter.gzip.GZIPFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>gzipFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>
  <!--gzip compress filter-->

18.http缓存cacheFilter，和gzipFilter共同用于提高用户性能

<!-- cache filter-->
  <filter>
    <filter-name>cacheFilter</filter-name>
    <filter-class>cn.dreampie.common.web.filter.cache.CacheFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>cacheFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>
  <!--cache filter-->
