由于一些问题，我刚刚将我的应用程序从 Grails 3.2.0 升级到3.2.1 ，并且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。

我收到以下异常：

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.authentication.dao.AbstractUserDetailsAuthenticationProvider.authenticate(AbstractUserDetailsAuthenticationProvider.java:144)

    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)

这仅在我们将它部署在 Apache Tomcat（使用8.5.6）上时才会失败，但它在使用grails run-app.

以下是修改后的依赖build.gradle项（其余配置与create-app生成的相同）：

// "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"

相同的设置在 Grails 3.2.0 中工作。

关于这个例外的任何想法？

似乎是 Grails 3.2.1 本身的问题。发出跟踪的 grails/grails-core#10244。

解决方法是limitScanningToApplication在您的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
    }
}
