我想在单独的文件中添加用户名和密码。

Answer 1

您可以使用：

 <context:property-placeholder location="classpath:myapp.properties" />

将属性文件添加到您的资源文件夹，确保它包含您的属性

myapplication.username=soguha9@gmail.com
myapplication.password=soham
myapplication.authorities=ROLE_USER

然后在您的用户服务中使用如下属性：

 <property name="username" value="${myapplication.username}" />
 <property name="password" value="${myapplication.password}" />
 <property name="authorities" value="${myapplication.authorities}" />

Answer 2

<authentication-manager>
    <authentication-provider user-service-ref="userServiceBean">        
    </authentication-provider>
</authentication-manager>

您可以拥有自定义用户服务，它可以从属性文件中读取用户详细信息。

Answer 3

如Spring Security 参考指南中所述，您可以将user-service指向包含所需信息的属性文件。

在src/main/resources创建一个属性文件users.properties 。

soguha9@gmail.com=soham123,ROLE_USER,enabled

然后将user-service指向这个文件

<user-service properties="classpath:users.properties" />
