升级到3.2.1后，用户身份验证失败

Question

我刚刚将我的应用从Grails 3.2.0升级到3.2.1由于一些问题以及用户身份验证开始失败。我正在使用Grails Spring Security Core插件版本3.1.1。

，我发现了以下异常：

org.springframework.security.authentication.InternalAuthenticationServiceException: 
    Cannot cast object 'User(email:user@example.com)' with class 'com.test.User' to class 'com.test.User' 
    at org.springframework.security.authentication.dao.DaoAuthenticationProvider.retrieveUser(DaoAuthenticationProvider.java:126)

    at org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter.doFilter(AbstractAuthenticationProcessingFilter.java:212) 

Caused by: org.codehaus.groovy.runtime.typehandling.GroovyCastException:

    at grails.plugin.springsecurity.userdetails.GormUserDetailsService$_loadUserByUsername_closure1.doCall(GormUserDetailsService.groovy) 

，当我们在Apache Tomcat上部署这只是失败（使用8.5.6），但它工作正常发展与grails run-app。

下面是改性的依赖关系在build.gradle（其余的配置是相同的通过创建应用内所产生）：

// "compile" changed to "provided" 
provided "org.springframework.boot:spring-boot-starter-tomcat" 
compile "org.grails.plugins:spring-security-core:3.1.1" 
compile "org.grails.plugins:asynchronous-mail:2.0.0.RC4" 
compile "org.mongodb:bson:3.3.0" 
compile "org.codehaus.groovy.modules.http-builder:http-builder:0.7.1" 
runtime "mysql:mysql-connector-java:5.1.39" 
// https://github.com/spring-projects/spring-boot/issues/6761 
runtime "com.google.code.gson:gson:2.5" 
// Commented this to avoid issue (https://github.com/grails/grails-core/issues/10196) 
//provided "org.codehaus.groovy:groovy-ant" 

的相同的设置是在Grails的3.2.0工作。

有关此异常的任何想法？

似乎是Grails 3.2.1本身的一个问题。问题跟踪grails/grails-core#10244。

解决方法是在你的grails-app/init/PACKAGE/Application.groovy

import grails.boot.GrailsApp 
import grails.boot.config.GrailsAutoConfiguration 

class Application extends GrailsAutoConfiguration { 
    static void main(String[] args) { 
     GrailsApp.run(Application, args) 
    } 

    @Override 
    boolean limitScanningToApplication() { 
     return false 
    } 
}
