The evening saw the third chapter of the tutorial .... Feel Shiro string permission is very useful .... But there are too few examples of tutorials ..... And some of the places are not very clear .... So I tested it myself .... Record the results of the test ....(1) *:viewThis type of string permission can match User:view,qwer:view, but cannot match qwe:qwe:view ...This means that the beginning of the * cannot match a string with a colon(2) user:*Can match User:view also can match user:view:qwe

Apache Shiro is a security framework for Java. Shiro can be very easy to develop a good enough application, not only can be used in the javase environment, but also can be used in the Java EE environment.The basic function points are as follows:Authentication : identity Authentication/login, verify that the user has the corresponding identity;Authorization : authorization, which is authentication of permissions, verifies that a authenticated user has

1.1 IntroductionApache Shiro is a security framework for Java. Currently, there are more and more people using Apache Shiro, because it is fairly simple, compared to spring security, it may not be as powerful as spring security, but it may not need to be as complex as it actually works. So the use of small and simple Shiro is enough. For the two of them in the end which is good, this does not have to struggle, can be easier to solve the project proble

{case (key, value) = > value.tostring (). Split ("\\s+"); Map (Word = > (word, 1)). Reducebykey (_ + _) Where the Flatmap function converts a record into multiple records (One-to-many relationships), the map function converts a record to another record (one-to-one relationship), and the Reducebykey function divides the same data into a bucket and calculates it in key units. The specific meaning of these functions can be referred to: Spark transformation. Step 4: Save the resulting rdd dataset to

Apache Shiro learning record 4 and apacheshiro record 4 I read the third chapter of the tutorial today... it's about authorization ...... as before ..... I also studied it myself .... I think how to read the tutorial ..... in general, there are a few excellent tutorials .... however, in some cases, it is too little .... and these places are quite difficult .. for example, section 3.5 Authorizer, PermissionR

Apache Thrift is an efficient framework for Facebook to implement remote service calls that support multiple programming languages.Objective:There are a number of popular service invocation methods, such as a WEB service based on a SOAP message format, a RESTful service based on a JSON message format, and so on. The data transmission methods used include Xml,json, but the XML is too large, the transmission efficiency is low, the JSON is small and nove

SHiro supports three different ways of authorizing:1. Programming: By writing If/else Authorization code block complete:Subject Subject = securityutils.getsubject (); if (Subject.hasrole ("admin")) { // have permission else { // No permissions 2.
