Spring Security权限注解-原创手记-慕课网

启用注解

@EnableGlobalMethodSecurity(prePostEnabled = true)

正常启用开启那个注解就行，下面放下我的配置

package com.fedtech.sys.provider.config.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.redis.RedisTokenStore;

import javax.annotation.Resource;

/**

 */
@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Resource
    RedisConnectionFactory redisConnectionFactory;
    @Resource
    private TokenStore tokenStore;

    @Bean
    public TokenStore redisTokenStore() {
        return new RedisTokenStore(redisConnectionFactory);
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.tokenStore(tokenStore);
    }
}

角色

    /**

     *
     * @param query {@link UserQuery}
     *
     * @return com.fedtech.common.util.result.R

     * @author <a href="mailto:njpkhuan@gmail.com"> huan </a>
     * @date 2021/2/20

     */
    @GetMapping("select")
    @PreAuthorize("hasAuthority('admin')")
    public R selectUser(UserQuery query) {
        UserDto dto = userService.selectUser(query);
        return R.successWithData(userMapper.dto2View(dto));
    }

权限

默认的是DenyAllPermissionEvaluator，所有权限都拒绝，所以要自定义

自定义处理逻辑

我是把权限放到了自定义的userDetails里面
