Question

当我尝试添加另一个数据源时出现问题（grails 2.1.2，mysql-connector-java 5.1.21）

在配置文件中添加了第二个数据源（dataSource_customer）

dataSource {
    url ="jdbc:mysql://localhost/defsource"
    username = "defsource"
    password = "defsource"
}

dataSource_customer {
    url ="jdbc:mysql://localhost/customer_db"
    username = "customer"
    password = "customer"
}

2定义了一个新类，将datasource设置为customer

class SensitiveDataExample {
    String analysisName

    static constraints = {
        analysisName nullable: false, blank: false, maxSize: 50
    }

    static mapping = {
        datasource('customer')
    }
}

有了这个，我可以毫无问题地访问SensitiveDataExample。但是，当我尝试访问任何其他域对象时，我得到以下异常

初步故障排除表明传递给SaveOrUpdateEvent（）及之后的（数据）源为空。

我尝试将数据源显式添加为其他域对象的DEFAULT，但没有帮助。

如果我只是注释掉dataSource_customer，则不会出现此异常。

添加另一个数据源后，默认数据源上的“IllegalArgumentException：null source”（Grails 2.1.2）
