Grails 3:覆盖doWithSpring中的服务

Question

在 grails 2 中，覆盖 XPlugin.groovy 中的 bean 只需要在 doWithSpring(( 方法中重新定义服务：

def doWithSpring = {
    tokenStorageService(TokenStorageProxyService) { it.autowire = 'byName' }
}

我开始用Grails 3编程，已经有过Grails 2的经验，并在新插件中尝试了同样的覆盖，因为我正在创建一些现有Grails 2插件的Grails 3版本：

Closure doWithSpring() { {->
    tokenStorageService(TokenStorageProxyService) {
        it.autowire = 'byName'
    }
} }

我做了一些集成测试：

@Integration
class SecurityServiceIntegrationSpec extends Specification {
    SecurityService securityService
    TokenStorageProxyService tokenStorageService
...
}

运行测试时，出现错误：

org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'grails.plugin.springsecurity.rest.token.storage.jwt.JwtTokenStorageService' to required type 'com.b2boost.grails3.auth.client.TokenStorageProxyService' for property 'tokenStorageService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'grails.plugin.springsecurity.rest.token.storage.jwt.JwtTokenStorageService' to required type 'com.b2boost.grails3.auth.client.TokenStorageProxyService' for property 'tokenStorageService': no matching editors or conversion strategy found

似乎默认的 JwtTokenStorageService 尚未被我的 TokenStorageProxyService 覆盖，导致在服务连接到集成测试时出现 ConversionNotSupportedException。如何在插件中覆盖服务？

Answer 1

经过一番调查，我的自定义模块似乎是在 Spring 安全休息后加载的。因此，来自SSR的tokenStorageService覆盖了我的服务，而相反的情况应该发生：

正在配置我的模块...

。完成配置我的模块

正在配置弹簧安全核心...

。完成 Spring 安全核心的配置

正在配置 Spring Security REST 2.0.0.M2...

。完成 Spring Security REST 的配置

在MyModuleGrailsPlugin.groovy中添加以下行可确保模块以正确的顺序加载：

def loadAfter = [
    'springSecurityRest'
]
