[英]There is no PasswordEncoder mapped for the id “null” in Spring Security
[英]Spring Security XML based configuration : java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"
尝试使用基于 spring security 5 的 xml 配置来测试简单的身份验证。 我有这个错误,这里是我的 XML 配置文件
spring-security.xml
<beans:beans
xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd">
<http auto-config="true">
<intercept-url pattern="/admin"
access="hasRole('ROLE_ADMIN')" />
</http>
<authentication-manager>
<authentication-provider>
<user-service>
<user name="admin" password="1234"
authorities="hasRole(ROLE_ADMIN)" />
</user-service>
</authentication-provider>
</authentication-manager>
</beans:beans>
spring-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean

<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
我应该添加任何配置来支持密码编码吗? 这是我的控制器
package com.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HomeController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home() {
return "home";
}
@RequestMapping(value = "/admin", method = RequestMethod.GET)
public String privateHome() {
return "privatePage";
}
}
对于我的 web.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">

我正在使用 spring mvc 5.0.2.RELEASE 谢谢。
对于那些面临同样问题的人,解决方案是将此配置添加到 spring-securit。 xml
<authentication-manager>
<authentication-provider>
<password-encoder hash="bcrypt" />
</authentication-provider>
之后,身份验证应该可以正常工作。
