RuntimeError: Compression requires the (missing) zlib module

安装 setuptools 报的错误,安装 zlib 和 zlib_devel 两个包

rpm -ivh zlib-1.2.3-29.el6.x86_64.rpm

 rpm -ivh zlib-devel-1.2.3-29.el6.x86_64.rpm 

安装成功后重新编译 python2.7.2

"One or more types required to compile a dynamic expression cannot be found. Are you missing...

#事故现场:

  在一个.net 4.0 的项目中使用 dynamic,示例代码如下:

1 private static void Main(string[] args)
2 {
3     dynamic obj;
4     obj = new { name = "jack" };
5     Console.WriteLine(obj.name);
6 }

  在读取 obj.name 时,报错:

One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?

#解决方法:

  在项目中,添加 Microsoft.CSharp.dll 的引用;

Access restriction: The type BASE64Encoder is not accessible due to restrict on required library

Access restriction: The type BASE64Encoder is not accessible due to restrict on required library

    今天在写一个WebService程序时,用到了sun.misc.BASE64Encoder().encode(baos.toByteArray()); 但遇到了一个错误:

Access restriction: The type BASE64Encoder is not accessible due to restrict on required library  java/lib/rt.jar。

导入了这个jar可是还是不行,于是查了一下,解决方法是在project的build path里先删除JRE System Library,然后再添加一遍,就好了。

我也不知道为什么这么做,求大神解释~~

Android piles of RuntimePermissions requests, code improving


for example:

AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CAMERA" />


java:

import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;

    private final int REQUEST_CODE = 0xa01;

    //批量权限组。
    private String[] permissions = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};

    @Override

        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

                } else {
                    Log.d(TAG, permissions[i] + "已获得授权,无需重复请求权限。");
                }
            }
        } else {
            Log.d(TAG, "Android版本低于23,无需运行时请求权限。");

                            //在这里开始启动获得授权后的业务逻辑代码。
                        }

Apache Shiro 使用 RequiresPermissions with Spring...

Apache Shiro 使用 RequiresPermissions with Spring...

Via:

根据官方文档在启用Shiro 注解(例如,@RequiresRoles,@RequiresPermissions 等等)时,
需要Shiro 的Spring AOP 集成来扫描合适的注解类以及执行必要的安全逻辑。
只需添加这两个bean 定义到applicationContext-shiro.xml 中:

<beandepends-on="lifecycleBeanPostProcessor"/>

<bean>
    <property name="securityManager" ref="securityManager"/>
</bean>


但是,在使用Spring MVC 的情况下,会遇到:
Exception: org.hibernate.HibernateException: No Session found for current thread

解决方法:
将以上代码移至Spring MVC 的servlet 配置文件,如:applicationContext-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.2.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
    
    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <!-- 只应加装表现层Bean,否则可能引起问题 -->
    <!-- 此处只应该加载表现层组件,如果此处还加载dao层或service层的bean会将之前容器加载的替换掉,而且此处不会进行AOP织入,所以会造成AOP失效问题(如事务不起作用) -->
    <context:component-scan base-package="com.binaryoptions.controller">
    	<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <!-- 其他spring-mvc框架配置 -->
	
    <bean id="viewResolver"
                p:view        p:prefix="/views/"
        p:suffix=".jsp" />
		
    <!-- more bean definitions go here -->
    <!-- 为安全检查使用Shiro 的注解(例如,@RequiresRoles,@RequiresPermissions 等等)。 -->
    <!--   
        以下两个bean的配置是为了在Controller层使用元注释控制权限  
        如果使用spring-mvc一定要不要放在webroot的配置文件中  
     -->
    <beandepends-on="lifecycleBeanPostProcessor"/>

    <bean>
        <property name="securityManager" ref="securityManager"/>
    </bean>
	
    <bean>  
        <property name="exceptionMappings">  
            <props>  
                <prop key="org.apache.shiro.authz.UnauthorizedException">/403</prop>
            </props>  
        </property>
    </bean>

</beans>
