Odd number of characters异常

Java.lang.IllegalArgumentException: Odd number of characters. at org.apache.shiro.codec.Hex.decode(Hex.java:128) ~[shiro-core-1.3.2.jar:1.3.2] at org.apache.shiro.codec.Hex.decode(Hex.java:107) ~[shiro-core-1.3.2.jar:1.3.2] at org.apache.shiro.codec.Hex.decode(Hex.java:95) ~[shiro-core-1.3.2.jar:1.3.2] at org.apache.shiro.authc.credential.HashedCredentialsMatcher.getCredentials(HashedCredentialsMatcher.java:353) ~[shiro-core-1.3.2.jar:1.3.2] at org.apache.shiro.authc.credential.HashedCredentialsMatcher.doCredentialsMatch(HashedCredentialsMatcher.java:380) ~[shiro-core-1.3.2.jar:1.3.2] at org.apache.shiro.realm.AuthenticatingRealm.assertCredentialsMatch(AuthenticatingRealm.java:597) ~[shiro-core-1.3.2.jar:1.3.2]

原因一： 使用shiro登入认证的 return new SimpleAuthenticationInfo(token.getPrincipal(), password, salt, getName()); 传参数的时候password 要使用加密过的。

原因二：后面整合jwt 改成了

return new SimpleAuthenticationInfo(token, token, getName());

需要把这段去掉 不然也会报这个错

/**

     * 这个类也负责对form里输入的密码进行编码。
