自定义Realm继承AuthorizingRealm父类。 HashedCredentialsMatcher 实例化并设置加密算法。
源码：
public AuthorizingRealm(CredentialsMatcher matcher) {
this((CacheManager)null, matcher);
}
设置迭代次数：
public void setHashIterations(int hashIterations) {
if (hashIterations < 1) {
this.hashIterations = 1;
} else {
this.hashIterations = hashIterations;
}
}
最后把实例化HashedCredentialsMatcher对象通过父类构造方法设置。
源码：
public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
this.credentialsMatcher = credentialsMatcher;
}
public interface CredentialsMatcher {
boolean doCredentialsMatch(AuthenticationToken var1, AuthenticationInfo var2);
}
HashedCredentialsMatcher实现CredentialsMatcher接口
源码：
public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
Object tokenHashedCredentials = this.hashProvidedCredentials(token, info);
Object accountCredentials = this.getCredentials(info);
return this.equals(tokenHashedCredentials, accountCredentials);
}
