我正在尝试使用Spring Security进行非常简单的基本身份验证.我已正确配置命名空间,服务器中没有例外.在我的"servlet.xml"中,我获得了Spring Security的下一个:

<security:http>
    <security:http-basic></security:http-basic>
    <security:intercept-url method="POST" pattern="/**" access="ROLE_USER" />
</security:http>


<security:authentication-manager alias="authenticationManager">
    <security:authentication-provider>
        <security:user-service>
            <security:user name="cucu" password="tas" authorities="ROLE_USER" />
            <security:user name="bob" password="bobspassword" authorities="ROLE_USER" />
        </security:user-service>
    </security:authentication-provider>
</security:authentication-manager>

它几乎都是完美的:POST没有提示任何登录表单的POST方法,并且方法提示它.问题是,那也不是cucu,也bob不能登录那里.任何人都可以看到我做错了什么？

提前致谢!;-)

我在我的应用程序中实现了SAF(存储访问框架).我正在三星nexus 10上运行我的应用程序.它安装了Dropbox.但我无法在我的应用程序中看到dropbox.所以我的问题是:

Dropbox是否注册到SAF？如果是,还有别的东西,我需要在我的应用程序中将dropbox作为根文件夹之一提供吗？

目前,在我的应用中,我看到 - Google云端硬盘,图片,下载为我的根文件夹

使用设计模式会使java代码变慢吗？如果我使用额外的接口和语法结构(如类包装),我会得到很好的组织,但代码速度慢或不会使我的代码显着减慢？

我正在尝试使用log4j2从使用FileAppender切换到RollingFileAppender(与beta3和beta4 jar一起发生).

我把它配置为:

<RollingFile name="RollingFile" fileName="${logdir}/${filename}" 
    filePattern="${logdir}/app-%d{yyyy-MM-dd-hh-mm-ss}_%i.log" >
    <PatternLayout>
        <pattern>%d %p %C{1.} [%t] %m%n</pattern>
    </PatternLayout>
    <Policies>
        <OnStartupTriggeringPolicy/>
    </Policies>
    <DefaultRolloverStrategy max="20"/>
</RollingFile>  
        ...
<loggers>
          <root level="ERROR">
    <appender-ref ref="RollingFile"/>
    <appender-ref ref="STDOUT"/>
</root>
        ...

在代码中,我试图以这种方式获取记录器:

Logger logger = LogManager.getLogger(this.getClass());

但是当我运行它时我得到了这个异常:

2013-02-01 17:56:54,773 ERROR Unable to invoke method createAppender in class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile java.lang.reflect.InvocationTargetException

我正在尝试在Robotium中运行一些自动化测试.我的应用程序中有以下代码,用于设置选项菜单:

  public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
    com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.layout.logoutmenu, menu);
        return super.onCreateOptionsMenu(menu);
   }

我尝试使用代码单击Robotium中的菜单:

solo.sendKey(Solo.MENU);
solo.clickOnView(solo.getView(R.id.share)); //share is the id of the menu item

但是我的测试因错误而失败:

View is null and therefore cannot be clicked.

我也尝试使用下面的代码也失败了:

solo.clickOnView(solo.getView(R.id.logoutmenu));
solo.clickOnMenuItem("Share My Artists"); 

抱歉英语不好.我得到了我的项目spring-boot 1.1.8,Encountered Exception No CurrentSessionContext configured,然后我做了一些搜索,添加属性<property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>可以解决这个问题,但是

如何使用java类配置此属性？

更新:我改为Hibernate4.x方式来定义SessionFactory但仍然遇到同样的错误,请帮忙!

使用java 1.8和speing boot 1.1.8

我在Eclipse中有一个Maven项目,现在我需要添加数据库连接.我的教科书在Maven中完成了所有json教程.现在,在本章的JDBC中,他们使用的是SpringBoot.

我可以将项目转换为SpringBoot吗？或者启动SpringBoot并导入我以前的Maven类.

我可以在一个Tomcat上运行两个(或更多)Spring启动应用程序吗？

我有两个应用程序打包为war文件,我想在一个Tomcat服务器上运行它们.但是,当我部署它们时,我得到以下异常:

org.springframework.jmx.export.UnableToRegisterMBeanException: 
    Unable to register MBean [org.springframework.boot.actuate.endpoint.jmx.DataEndpointMBean@2361d8ee] with key 'dumpEndpoint'; 
    nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Endpoint,name=dumpEndpoint

每个Spring-boot应用程序注册的默认端点(如/ health等)都会发生冲突.是否有一些解决方法或不可能实现此设置？

谢谢你的回复!

每当启动应用程序spring boot时,我都会收到以下错误.

应用程序未能启动

描述:

com.base.model.AbstractDao中的字段会话需要一个无法找到的类型为'org.hibernate.SessionFactory'的bean.

行动:

考虑在配置中定义类型为'org.hibernate.SessionFactory'的bean.

我添加了我的应用程序的实现:
