我有一些JPEG图片,我想缩小.另一个要求是文件大小不应大于300kByte.

这是可能的,请帮我一个例子=)

我想知道如何使用Maven和Eclipselink 2.5生成静态元模型.通过在运行Eclipselink 2.4时将这些行添加到pom.xml,它运行良好.

// Generate meta model for eclipselink 2.4 (does not work for 2.5)
    <plugin>
                    <groupId>org.bsc.maven</groupId>
                    <artifactId>maven-processor-plugin</artifactId>
                    <version>1.3.1</version>
                    <executions>
                        <execution>
                            <id>process</id>
                            <goals>
                                <goal>process</goal>
                            </goals>
                            <phase>generate-sources</phase>
                            <configuration>
                                <compilerArguments>-Aeclipselink.persistencexml=src/main/resources/META-INF/persistence.xml</compilerArguments>
                                <processors>
                                    <processor>org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor</processor>
                                </processors>
                                <outputDirectory>${project.build.directory}/generated-sources/meta-model</outputDirectory>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>

但似乎自2.4以来出现了一些变化,因为我得到了以下错误:

[INFO] javac option: -proc:only
[INFO] javac option: -Aeclipselink.persistencexml=src/main/resources/META-INF/persistence.xml

在我的服务类中,我希望有类似的东西:

class ClientService {

  // Authorize
  // Returns true: Authorization successful
  // Returns false: Authorization failed
  public boolean authorize(String id, String password) {

  //Here I would like to check if an active transaction exists. 
  //If it exists, use that one, else create a new session and start 
  //a new transaction.
  //For example:
  Session session = HibernateUtil.getSessionFactory().getCurrentSession();
  if(!session.SOMEMETHOD_CHECK_IF_TRANSACTION_IS_ACTIVE) {
    session.beginTransaction();
  }

  Client client = clientDAO.get(id);

  if (client != null) {
    if (client.getPassword().equals(password)) {
      logger.debug("Authorization successful. ID: " + client.getId() + ", …

在JSF 2.0中是否可以为一个输入提供多个验证器？例如,假设我将写一个用户名,用户名必须包含8个字符.如果确定,则检查数据库中是否存在用户名.

<ice:inputText id="username" value="#{createClient.username}" maxlength="15">
  <-- something like this -->
  <f:validator validatorId="usernameValidator" validatorId="usernameExistValidator" />
</ice:inputText> 
<ice:message for="username" />

我正在使用JSF 2.0

我的管理部分中有一个表单,我将在列表中选择一些用户.

表单(selectusers.xhtml)将这些用户添加到bean中的列表(SelectUsers.java).

在我选择了一些用户之后,我会将用户列表从SelectUsers.java传递到另一个bean(AddAddressBean.java)并继续以另一种形式添加信息(addadress.xhtml),其中设置了其他相关的属性为每个用户添加AddAddressBean.

我不知道如何实现它.我想AddAddressBean.java应该是独立的(所以我可以将它与其他bean一起使用),所以我更喜欢AddAddressBean.java不知道其他bean.

你能帮我么？=)

我的Maven项目已经增长,所以我决定尝试制作一个Maven多模块项目.

我认为它似乎工作正常,除了Eclipselink元模型类生成.

这是运行时的输出,mvn clean generate-sources这是预期的:

我已经将ABP框架部署在Kubernetes集群中。

存在以下部署：

• 雷迪斯
• MSSql
• 认证服务器
• HttpApi.Host
• Nginx 入口/反向代理带有 https 终止，集群内没有加密。

因此，AuthServer、HttpApi.Host 正在侦听端口 80 / http，而 nginx 正在侦听 https。配置/Helm 值如下：

use-forwarded-headers: "true"
use-proxy-protocol: "true"
use-gzip: "true"

到目前为止一切顺利，部署后我可以进入 Swagger 并授权：

通过检查 AuthServer 日志可以确认这一点：

[19:12:39 INF] CORS policy execution successful.
[19:12:39 INF] The request URI matched a server endpoint: Token.
[19:12:39 INF] The token request was successfully extracted: {
  "grant_type": "authorization_code",
  "code": "[redacted]",
  "client_id": "foobar_Swagger",
  "redirect_uri": "https://api.staging.foobar.io/swagger/oauth2-redirect.html"
}.
[19:12:39 INF] The token request was successfully validated.

但是，现在我想使用 Swagger 来确保与端点的连接正常工作，因此我尝试第一个 GET 端点：

如您所见，有 500 …

我在eclipse 3.6中创建了一个新的Dynamic Web Project.

我添加了一个Tomcat 7.0服务器,并在jsf文件中选择"Run on server".工作正常!

我将它添加到SVN存储库以与其他人共享.

我关闭了Eclipse.

我创建了一个新的工作空间来检查一切是否正常工作.签出与上面相同的项目.

我添加了一个Tomcat 7.0服务器,并在与以前相同的文件中选择"在服务器上运行".这导致404:"HTTP状态404 .... - 描述所请求的资源()不可用."

这是为什么？？这真奇怪!你不觉得吗？你能帮我么？

最好的祝福
