我需要在Spring Security Implementation的某些部分使用XML Configuration。我现在所关心的只是JWT授权,JWT传递给我。使用Spring Security我确定用户是否有权访问REST API端点。我不能使用Java配置或@PreAuthorize注释。
作为我最初使用@PreAuthorize时的FYI或类似的方法: .antMatchers( “/学生/ **”)访问( “#oauth2.hasScope( '范围:管理员')”);
。一切都很好。当我被迫转向XML配置并使用security:intercept-url方法时,出现了这个问题。
我得到的错误是:
“message”:“无法评估表达式 '#oauth2.hasScope(' 范围:管理员 ')'“
例外是:
java.lang.IllegalArgumentException:无法计算表达式 '#oauth2.hasScope(' 适用范围:联系 ')'
在org.springframework.security.access.expression.ExpressionUtils.evaluateAsBoolean(ExpressionUtils.java:30)〜[spring-security-core-5.0.3.RELEASE.jar:5.0.3.RELEASE]
...为了简洁,删除异常行为...... 引起: org.springframework.expression.spel.SpelEvaluationException:EL1011E: 方法调用:尝试调用方法hasScope(java.lang.String) null上下文对象
XML配置:
<!-- only enable this when deving -->
<!-- <security:debug /> -->
<bean id="securityConfig"
class="com.wmay.config.SecurityConfig">
</bean>
<bean id="resourceServerConfig"
class="com.wmay.config.ResourceServerConfig">
</bean>
<bean id="methodSecurityConfig"
class="com.wmay.config.MethodSecurityConfig">
</bean>
<security:http pattern="/**" use-expressions="true" auto-config="true">
<security:intercept-url pattern="/students/**"
access="#oauth2.hasScope('Scope:Admin')"/>
</security:http>
代码段:
@Override
public void configure(HttpSecurity httpSecurity) throws Exception { log.info("Configuring HttpSecurity");
httpSecurity.csrf().disable(); httpSecurity.cors().configurationSource(corsConfigurationSource());
//@// @formatter:off
httpSecurity
.requestMatchers()
.and().authorizeRequests()
.antMatchers("/actuator/**").permitAll()
.antMatchers(HttpMethod.OPTIONS, "/**").permitAll();
// @formatter:on
}
@Override
protected MethodSecurityExpressionHandler createExpressionHandler() {
log.info(
"Enabling OAuth2 Method Expression Handler.");
return new OAuth2MethodSecurityExpressionHandler();
}
答案 0 :(得分:0)
我明白了。我需要在XML配置文件中添加更多条目。
