Spring Security在所有角色名称中添加了前缀“ROLE_”？

java spring spring-mvc spring-security role

我的 Web 安全配置中有以下代码：

 @Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .authorizeRequests()
            .antMatchers("/api/**")
            .hasRole("ADMIN")
            .and()
            .httpBasic().and().csrf().disable();

}

因此，我在数据库中添加了一个具有“ADMIN”角色的用户，当我尝试使用此用户进行loggin时，我总是收到403错误，然后我启用了spring的日志，并找到了这行：

2015-10-18 23:13:24.112 DEBUG 4899 --- [nio-8080-exec-1] o.s.s.w.a.i.FilterSecurityInterceptor    : Secure object: FilterInvocation: URL: /api/user/login; Attributes: [hasRole('ROLE_ADMIN')]

为什么Spring Security正在寻找“ROLE_ADMIN”而不是“ADMIN”？

答案 1

默认情况下，Spring Security会添加前缀“ROLE_”。

在春季4中，有两种方法，并在课堂上定义。这两种方法仅检查您的自定义角色名称，而不添加前缀。定义如下：hasAuthority()hasAnyAuthority()org.springframework.security.access.expression.SecurityExpressionRootROLE_

public final boolean hasAuthority(String authority) {
    return hasAnyAuthority(authority);
}
public final boolean hasAnyAuthority(String... authorities) {
    return hasAnyAuthorityName(null, authorities);
}
private boolean hasAnyAuthorityName(String prefix, String... roles) {
    Set<String> roleSet = getAuthoritySet();

    for (String role : roles) {
        String defaultedRole = getRoleWithDefaultPrefix(prefix, role);
        if (roleSet.contains(defaultedRole)) {
            return true;
        }
    }

    return false;
}
private static String getRoleWithDefaultPrefix(String defaultRolePrefix, String role) {
    if (role == null) {
        return role;
    }
    if (defaultRolePrefix == null || defaultRolePrefix.length() == 0) {
        return role;
    }
    if (role.startsWith(defaultRolePrefix)) {
        return role;
    }
    return defaultRolePrefix + role;
}

用法示例：

<http auto-config="false" use-expressions="true" pattern="/user/**"
      entry-point-ref="loginUrlAuthenticationEntryPoint">
    <!--If we use hasAnyAuthority, we can remove ROLE_ prefix-->
    <intercept-url pattern="/user/home/yoneticiler" access="hasAnyAuthority('FULL_ADMIN','ADMIN')"/>
    <intercept-url pattern="/user/home/addUser" access="hasAnyAuthority('FULL_ADMIN','ADMIN')"/>
    <intercept-url pattern="/user/home/addUserGroup" access="hasAuthority('FULL_ADMIN')"/>
    <intercept-url pattern="/user/home/deleteUserGroup" access="hasAuthority('FULL_ADMIN')"/>
    <intercept-url pattern="/user/home/**" access="hasAnyAuthority('FULL_ADMIN','ADMIN','EDITOR','NORMAL')"/>
    <access-denied-handler error-page="/403"/>
    <custom-filter position="FORM_LOGIN_FILTER" ref="customUsernamePasswordAuthenticationFilter"/>
    <logout logout-url="/user/logout"
            invalidate-session="true"
            logout-success-url="/user/index?logout"/>
    <!-- enable csrf protection -->
    <csrf/>
</http>   <beans:bean id="loginUrlAuthenticationEntryPoint"
            class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
    <beans:constructor-arg value="/user"/>
</beans:bean>
