springsecurity Password Md5+salt configuration

The password is MD5 encrypted with a salt value.

For example Username:name Password:pass salt to username

The plaintext password is pass{name} parentheses for the salt corresponding to the username, and then the plaintext password is encrypted

The springsecurity is configured as follows

 <authentication-manager  alias= "AuthenticationManager"  >     <authentication-provider ref= "Authenticationprovider" >  </authentication-provider>  </authentication-manager>       <beans:bean id= " Authenticationprovider " class=" Org.springframework.security.authentication.dao.DaoAuthenticationProvider " >      <beans:property name= "Userdetailsservice"  ref= " Myuserdetailservice " />      <beans:property name=" Passwordencoder " ref=" Passwordencoder "/>     <beans:property name=" Saltsource " ref=" Saltsource "/>   </beans:bean>    <beans: Bean id= "Passwordencoder"   class= " Org.springframework.security.authentication.encoding.Md5PasswordEncoder "/><beans:bean id=" SaltsouRce " class=" Org.springframework.security.authentication.dao.reflec tionsaltsource ">     <beans:property name= "Userpropertytouse"  value= "username"/></beans:bean>

Add Passwordencoder and Saltsource two properties to the Authenticationprovider configuration

This configuration is over.

At the same time, Springsecurity provides the Md5passwordencoder class to implement MD5 encryption

Md5passwordencoder MD5 = new Md5passwordencoder (); String result = Md5.encodepassword ("User", "user"); SYSTEM.OUT.PRINTLN (result);

Md5.encodepassword two parameters, the previous one is password, the latter is the salt salt value

At the same time, website http://md5jiami.51240.com/also provides the function of online encryption
