Spring security vs Apache Shiro [duplicate]

Answer 1

Shiro is better to use. Its code much simple which provides you flexibility to extend it and provide your custom behaviour wherever needed. It also provides internal cache implementation of Ehcache through which you can replicate session on server clusters. If you are going to design RBAC(Role based access control) system for your application it will provide you flexibility to handle asset level permission and its access control mechanism is much flexible as compared to spring security.

Answer 2

I have evaluated both Shiro and Spring security. The main advantage that people claim about Shiro is simplicity, but I believe that Spring Security (3.0) is not crazy complicated. It took me almost the same amount of lines of configuration to set up. Also Spring Security is much better documented than Shiro. But the main issue with Shiro it is that it doesn't support OAuth or Digest Authetication (they are planning to include it in the future https://issues.apache.org/jira/browse/SHIRO-20 ). My conclusion: Today I would go for spring security.

Answer 3

Spring Security and Shiro both sets awesome with Spring framework. i have tested both of them . for me spring security was easy to integrate and is totally understandable according to developer points of view. and Shiro is also easy to integrate but for me Spring is more easy to integrate.

Answer 4

Many of the Shiro developers use Spring for their applications, so Shiro works beautifully in Spring environments. The general feedback we've received thus far is that Shiro is also far easier to understand (for most people) than Spring Security.

If you want full Session clustering support across any web container however, only Shiro will support this easily. Shiro's crypto is also very simple/easy to use.

Choose which fits your mental model best - both will work great in Spring environments.

Answer 5

I have recently had to evaluate both shiro and spring security. We went with spring security (in fact we extended spring security to use the shiro permission strings in a better way - with instance variables on annoations).

Spring Security

• under active development.
• has much more community support.
• Spring security has extensions providing support for both Oauth and kerberos and SAML.

Shiro

• Does not support saml or Oauth.
• Makes no mention of supporting before and after security policies.
• Active development seems limited, the website still contains erroneous information.
