无法自动装配字段：private org.springframework.security.crypto.password.PasswordEncoder;

Question

我正在使用Java配置而非XML迁移到Spring Security 4.0.1。当我通过Autowire注入 PasswordEncoder 时，它会给出以下错误：

  

HTTP状态500 - org.springframework.beans.factory.BeanCreationException：创建bean名称为'scopedTarget.UsersComponent'的bean时注入自动装配依赖项失败；嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private org.springframework.security.crypto.password.PasswordEncoder com.car.component.impl.UsersComponentImpl.passwordEncoder；嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有找到类型为[org.springframework.security.crypto.password.PasswordEncoder]的合格bean，以满足此依赖项：期望至少有1个bean可以作为此依赖项的自动装配候选项。依赖注释：{@org.springframework.beans.factory.annotation.Autowired（required = true）}

我会发布所有我的配置文件。我不知道我错在哪里。

JSF标签，一个普通的HTML表单，同时注册了org.springframework.web.servlet.DispatcherServlet和javax.faces.webapp.FacesServlet - 这是一个不好的组合。 - Tiny

你正在尝试同时使用JSF和Spring MVC，这是不允许的。然而你可以在Spring平台上使用JSF（Spring和Spring MVC是完全不同的。Spring是一个庞大的框架 - 一个有多个模块的Java平台，Spring MVC仅仅是其中之一。Spring DI能够与JSF一起使用，但是Spring MVC和JSF不能一起使用，因为它们都是MVC框架）。 - Tiny

同意你的观点。我不需要 Spring MVC 的那一部分。实际上，我的应用程序使用的是 Spring 3.1 和 Spring Security 3.1（XML 配置）。并且正在使用 Spring DI。我需要将其升级到 Spring Security 4.0，并决定使用 Java 配置来完成。你能指导我如何做吗？我想删除 Spring MVC 部分，因为我对它不感兴趣。 - Alina

Answer 1

使用这个bean：

@Bean
PasswordEncoder getEncoder() {
    return new BCryptPasswordEncoder();
}

- Amine

---

请问如何用XML编写它？ - 404NotFound

Answer 2

您必须将密码编码器设置为bean:

@Bean
public PasswordEncoder passwordEncoder() {
    return new ShaPasswordEncoder();
}

然后您可以进行自动装配。

我不能使用import org.springframework.security.authentication.encoding.ShaPasswordEncoder; 它在Spring Security 4中已经被弃用了!! - Alina

@Alina 但是在您上面的代码中已经使用了 ShaPasswordEncoder。使用任何密码编码器都可以。 - holmis83

@holmis83，我应该在哪里指定这个bean？我试图在服务类中指定它，但是它没有起作用。我也在应用程序类中使用它。 - cammando

@cammando 你应该放在一个带有 @Configuration 注释的类里面。 - holmis83

Answer 3

@Bean
public PasswordEncoder encoder() {
    return new BCryptPasswordEncoder();
}
