小编Dav*_*ave的帖子

我正在使用Spring 3.1.0.RELEASE.我的命令对象中有这个字段...

public Set<EventFeed> getUserEventFeeds() {
    return this.userEventFeeds;
}

在我的Spring JSP页面上,我想显示所有可能的事件源的复选框列表,然后检查复选框,如果用户在其集合中有一个.我希望在每个复选框周围都有一些特殊的HTML格式,所以我正在尝试......

<form:form method="Post" action="eventfeeds.jsp" commandName="user">
    ...
        <c:forEach var="eventFeed" items="${eventFeeds}">
        <tr>
            <td><form:checkbox path="userEventFeeds" value="${eventFeed}"/></td>
            <td>${eventFeed.title}</td>
        </tr>
        </c:forEach>
    ...

但是,如果一个项目在集合中,则默认情况下不会检查这些项目.我该怎么做呢？这是我在控制器类中使用的活页夹...

@InitBinder
public void initBinder(WebDataBinder binder) {
    binder.registerCustomEditor(EventFeed.class, new EventFeedEditor());
}

private class EventFeedEditor extends PropertyEditorSupport {
    @Override
    public void setAsText(String text) throws IllegalArgumentException {
        setValue(eventFeedsDao.findById(Integer.valueOf(text)));
    }

    @Override
    public String getAsText() {
        return ((EventFeed) getValue()).getId().toString();
    }
}

我正在使用Spring 3.1.1.RELEASE和Hibernate 4.1.0.Final.我得到了"无法初始化代理 - 无会话"异常,尽管事实上我正在将相关方法调用包装在@Transactional注释中.这是我的方法......

@Service("teacherImportService")
public class TeacherImportServiceImpl extends AbstractmyprojectService 
{
    …
    @Transactional
    @Override
    public void saveUserObject(final JsonObject jsonData)  
    {
        …
        final myprojectOrganization myprojectOrg = myprojectOrgDao.findBymyprojectOrgId(myprojectSchoolId);
        final Organization school = myprojectOrg != null ? myprojectOrg.getOrg() : null;
            …
        final Address address = new Address();
        address.setState(school.getState());    // error occurs here

我还需要做些什么来保证交易发生？我在我的应用程序上下文中包含了"<tx:annotation-driven />",我在下面包含了它

<context:component-scan base-package="org.mainco.subco" />
...
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${test.mysql.dataSource.driverClassName}" />

    <property name="username" value="${test.mysql.db.user}" />
    <property name="password" value="${test.mysql.db.password}" />
</bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property …

我使用Spring 3.2.6.RELEASE,JUnit 4.11和DWR 3.0.0-rc2.我的问题是,在运行Spring-JUnit集成测试时,如何模拟正在运行的东西org.springframework.context.support.GenericApplicationContext？

我试过这个:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml", "classpath:dwr-context.xml" })
@WebAppConfiguration
public class MyServiceIT 
{}

我的"dwr-context.xml"文件设置为

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
       http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">

  <dwr:configuration>
    <dwr:convert class="java.lang.StackTraceElement" type="bean"/>
  </dwr:configuration>
  <dwr:annotation-config id="annotationConfig" />
  <dwr:annotation-scan base-package="org.mainco.subco" scanDataTransferObject="true" scanRemoteProxy="true" />
  <dwr:url-mapping />
  <dwr:controller id="dwrController" debug="false" /> 

  <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="alwaysUseFullPath" value="true"/>
    <property name="urlMap">
      <map>
        <entry key="/dwr/**" value-ref="dwrController" />
      </map>
    </property>
  </bean> 
</beans>

但是,我的所有JUnit测试最终都会因以下异常而死:

("java.lang.IllegalStateException:WebApplicationObjectSupport实例[org.directwebremoting.spring.DwrController@11297ba3]不在WebApplicationContext中运行,而是在:org.springframework.context.support.GenericApplicationContext@4e513d61")中运行.

如果我能弄明白如何欺骗系统运行,GenericApplicationContext我就会解决这个问题. …

我使用Wildfly 10.0.0.CR2和Java 8.我让Wildfly在端口8080上侦听http连接,并且过去使用此命令关闭服务器...

./jboss-cli.sh --connect command=:shutdown

HOwever,偶尔,我无法访问此工具,即使服务器仍在运行.请注意我的Mac下面的交互...

Daves-MacBook-Pro-2:bin davea$ ./jboss-cli.sh --connect command=:shutdown
Failed to connect to the controller: The controller is not available at localhost:9990: java.net.ConnectException: WFLYPRT0023: Could not connect to http-remoting://localhost:9990. The connection timed out: WFLYPRT0023: Could not connect to http-remoting://localhost:9990. The connection timed out

Trying ::1...
telnet: connect to address ::1: Connection refused

我的问题是,什么是关闭JBoss服务器的万无一失的方法？注意我更喜欢不依赖于CLI工具的方法.

我正在使用Spring 3.2.11.RELEASE和JUnit 4.11.使用Spring mockMvc框架,如何检查返回JSON数据的方法是否包含特定的JSON元素？我有

    mockMvc.perform(get("/api/users/" + id))
        .andExpect(status().isOk())
        .andExpect(content().string("{\"id\":\"" + id + "\"}")); 

但这会检查与返回的字符串的完全匹配,我宁愿检查JSON字符串是否包含我的本地字段"id"包含的值.

我正在使用Rails 5来使用Rails缓存来存储Nokogiri对象.

我在config/initializers/cache.rb中创建了这个:

$cache = ActiveSupport::Cache::MemoryStore.new

我想存储以下文件:

$cache.fetch(url) {
  result = get_content(url, headers, follow_redirects)
}

但我收到这个错误:

我正在使用Python 3.7和Django.我有以下型号,带有另一个型号的外键......

class ArticleStat(models.Model):
    objects = ArticleStatManager()
    article = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='articlestats')
    ...

    def save(self, *args, **kwargs):
        if self.article.exists():
            try:
                article_stat = ArticleStat.objects.get(article=self.article, elapsed_time_in_seconds=self.elapsed_time_in_seconds)
                self.id = article_stat.id
                super().save(*args, **kwargs, update_fields=["hits"])
            except ObjectDoesNotExist:
                super().save(*args, **kwargs)

如果相关的外键存在,我只想保存它,否则,我注意到错误结果.做这样的事情的标准Django/Python方法是什么？我以为我读过我可以使用".exists()"(检查一个对象是否存在),但我得到一个错误

AttributeError: 'Article' object has no attribute 'exists'

编辑:这是我必须检查的单元测试...

    id = 1
    article = Article.objects.get(pk=id)
    self.assertTrue(article, "A pre-condition of this test is that an article exist with id=" + str(id))
    articlestat = ArticleStat(article=article, elapsed_time_in_seconds=250, hits=25)
    # Delete the article
    article.delete()

我正在使用Java 8，JUnit 4.12，Spring 4和Hibernate 5.2.12.Final。我想测试一个Hibernate方法，在其中更新一些行。方法看起来像这样

        final CriteriaBuilder qb = m_entityManager.getCriteriaBuilder();
        final CriteriaUpdate<FailedEvent> q = qb.createCriteriaUpdate(FailedEvent.class);
        final Root<FailedEvent> root = q.from(FailedEvent.class);
        q.where(qb.and( qb.equal(root.get(FailedEvent_.objectId), objectId) ));
        q.set(root.get(FailedEvent_.flaggedForDelete), true);
        affectedRows = m_entityManager.createQuery(q).executeUpdate();
     return affectedRows > 0;

我有以下JUnit测试来验证这一点

public class FailedEventDaoTest extends AbstractTransactionalJUnit4SpringContextTests
...

    @Test
    public final void testFlagForDeleteByObjectId()
    {
            final String eventId = "testId";
            final FailedEvent event = failedEventDao.findByEventId(eventId);
            Assert.assertFalse("A pre-condition fo this test is that an failed_event record with id \"" + eventId + "\" have a non-empty object id.", StringUtils.isEmpty(event.getObjectId()));
            Assert.assertTrue(failedEventDao.flagForDeleteByObjectId(event.getObjectId())); …

我正在尝试在 CentOS 7 上构建支持 SSL 的 Python 3.9.1。

[myuser@server Python-3.9.1]$ which openssl
/usr/local/bin/openssl
[myuser@server Python-3.9.1]$ openssl version
OpenSSL 1.1.1g  21 Apr 2020

运行这个命令

sudo ./configure CPPFLAGS="-I/usr/local/openssl/include" LDFLAGS="-L/usr/local/openssl/lib" --with-ssl

接下来的“make”适用于 Python 3.7，但是当我在 3.9 上运行上面的代码然后运行 ​​make 时，我得到了这个输出

我正在使用Spring 3.1.2.RELEASE.如果我的日期字段格式不正确,我想在我的JSP上显示错误消息.我以为我会遵循所有正确的步骤.我在控制器中绑定了一个转换器......

@InitBinder
public void initBinder(final WebDataBinder binder) {
    final DateFormat dateFormat = new SimpleDateFormat(Contract.DATE_FORMAT);
    dateFormat.setLenient(false);

    // true passed to CustomDateEditor constructor means convert empty String to null
    binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
...
}

我在messages.properties文件中包含了这些错误消息(包含在Spring应用程序上下文中)

typeMismatch.activationDate=The activation date format should be of the form MM/dd/yyyy
typeMismatch.sampleUserForm.activationDate=The activation date format should be of the form MM/dd/yyyy

这是我正在使用的模型:

public class SampleUserForm

    private String middleName;
    private String lastName;
