小编Mic*_*fel的帖子

我想转换java.time.LocalDate成java.util.Date类型.因为我想将日期设置为JDateChooser.或者是否有支持java.time日期的日期选择器？

我在Question实体中有以下内容:

@NamedQuery(name = "Question.allApproved",
    query = "SELECT q FROM Question q WHERE q.status = 'APPROVED'")

和

@Enumerated(EnumType.STRING)
private Status status;

// usual accessors

我得到这个例外:

异常说明:编译查询时出错[Question.countApproved:SELECT COUNT(q) FROM Question q WHERE q.status = 'APPROVED'],第1行,第47列:无效的枚举等于表达式,无法将类型 [myCompnay.application.Status]的枚举值与非枚举值类型进行比较[java.lang.String].at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.deploy(EntityManagerSetupImpl.java:501)

我该如何解决？

我正在设置Spring Security来处理日志记录用户.我已经以用户身份登录,并在成功登录后被带到Access Denied错误页面.我不知道我的用户实际分配了什么角色,或者导致访问被拒绝的规则,因为我无法弄清楚如何为Spring Security库启用调试.

我的安全xml:

对于单元测试(如果需要,可以调用它们进行集成测试)我在Spring配置中配置了一个嵌入式数据库,如下所示:

<jdbc:embedded-database id="dataSource" type="H2">
    <jdbc:script location="classpath:schema_h2.sql" />
</jdbc:embedded-database>

现在,当从命令行运行测试时,它们工作正常,但最后我得到了一些错误(无害,但令人恼火):

WARN  2013-03-25 12:20:22,656 [Thread-9] o.s.j.d.e.H2EmbeddedDatabaseConfigurer 'Could not shutdown embedded database'

    at org.springframework.beans.factory.support.DisposableBeanAdapter.destroy(DisposableBeanAdapter.java:238) [spring-beans-3.2.1.RELEASE.jar:3.2.1.RELEASE]

现在,异常中包含的提示一般很好,但是如何将此属性添加到嵌入式数据源？我是否必须扩展它,手动配置它可以说,添加这样的"高级"功能？

我在Struts 2 + Spring IOC项目中使用Spring Security 3.

我在我的项目中使用过滤器,身份验证提供程序等.

我在Spring Boot应用程序中的Logback配置有问题.我希望我consoleAppender看起来像默认的Spring Boot控制台appender.如何从Spring Boot默认控制台appender继承模式？

以下是我的consoleAppender配置

<appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.classic.PatternLayout">
        <Pattern class="org.">
            %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
        </Pattern>
    </layout>
</appender>

如何@Lock为查询指定超时.我正在使用oracle 11g,我希望我可以使用类似的东西'select id from table where id = ?1 for update wait 5'.

我定义了这样的方法,

@Lock(LockModeType.PESSIMISTIC_WRITE)
Stock findById(String id);

它似乎永远锁定.我开始javax.persistence.lock.timeout=0了LocalContainerEntityManagerFactoryBean.jpaProperties,但没有受到影响.

在开始我的应用程序时,我会收到大量警告o.s.aop.framework.Cglib2AopProxy 'Unable to proxy method [public final void org.springframework.jdbc.core.support.JdbcDaoSupport.setDataSource(javax.sql.DataSource)] because it is final: All calls to this method via a proxy will be routed directly to the proxy.',大约有十几个功能.

现在我完全理解基于代理的方面不能应用于最终方法.但是,我没有(至少是故意的)尝试编织任何方面JdbcDaoSupport.我怀疑它来自<tx:annotation-driven />.我能做些什么来消除这些警告,或者更好的是,将这些类别排除在编织方面？

我试图在一个小型独立应用程序中一起使用spring数据和spring配置.

...
  public static void main( String[] args )
  {        
    ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class);
    ... 
  }

1.我的问题是如何在不使用的情况下发现spring数据存储库

<jpa:repositories base-package="foo.repositories" />

通过spring config？

2.如果没有,我可以以某种方式一起使用'ClassPathXmlApplicationContext'和'AnnotationConfigApplicationContext'吗？

如果我有以下配置:

<defaultCache timeToIdleSeconds="120"
        timeToLiveSeconds="120" />
<cache name="test"
        timeToLiveSeconds="300" />

timeToIdleSeconds缓存的价值是test什么？它是继承自默认缓存,因此等于120,还是采用手册中给出的默认值,即0(无穷大)？
