内容简介：use spring-security protect ResourceServer
來補一下怎麼保護 ResourceServer
套件依賴
build.gradle
buildscript {
ext {
springBootVersion = '1.5.2.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
jar {
baseName = 'ps-account'
version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
repositories {
mavenCentral()
}

compile('org.springframework.boot:spring-boot-starter-data-jpa')

}
spring-security-oauth2 spring-security-jw 是我們需另外加進來的
我們會有一些基礎的帳號或是角色的物件
帳號
Account.java
@Data
@Entity
@EntityListeners(AuditingEntityListener.class) //加這行 CreatedBy 才會生效
public class Account {
@Id
//@GeneratedValue
private String accountid;
@NotNull
@UniqueUsername(message = "Username already exists")
@Size(min = 5, max = 255, message = "Username have to be grater than 8 characters")
@Column(unique = true)
private String username;
private String email;
@JsonIgnore
@NotNull
@Size(min = 8, max = 255, message = "Password have to be grater than 8 characters")
private String password;
@NotNull
private boolean enabled = true;
@NotNull
private boolean credentialsexpired = false;
@NotNull
private boolean expired = false;
@NotNull
private boolean locked = false;
// @Formula("(select * from Role r where r.roleid in (select roleid from account_role ar where ar.accountid = accountid ))")
@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(name = "AccountRole", joinColumns = @JoinColumn(name = "accountid", referencedColumnName = "accountid", insertable = false, updatable = false),
inverseJoinColumns = @JoinColumn(name = "roleid", referencedColumnName = "roleid", insertable = false, updatable = false) )
private List<Role> roles;
@CreatedDate
@Column(name = "createddate")
private Date createddate;
@CreatedBy
@Column(name = "createdby")
private String createdby;
@LastModifiedDate
@Column(name = "lastmodifieddate")
private Date lastmodifieddate;
@LastModifiedBy
@Column(name = "lastmodifiedby")
private String lastmodifiedby;
}
角色
Role.java
@Data
@Entity
@EntityListeners(AuditingEntityListener.class) //加這行 CreatedBy 才會生效
public class Role {
@Id
private String roleid;
@NotNull
private String code;
@NotNull
private String label;
@CreatedDate
@Column(name = "createddate")
private Date createddate;
@CreatedBy
@Column(name = "createdby")
private String createdby;
@LastModifiedDate
@Column(name = "lastmodifieddate")
private Date lastmodifieddate;
@LastModifiedBy
@Column(name = "lastmodifiedby")
private String lastmodifiedby;
}
配置 ResourceServer Security
OAuth2ResourceServerConfig.java
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
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.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
/**
* Created by samchu on 2017/2/17.
*/
@Configuration
@EnableResourceServer
// prePostEnabled 很重要，可以讓你配置 @PreAuthorize("#oauth2.hasScope('account')") 在任何需要的方法上
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {
// 這邊配置這服務的 resourceId ，當 jwt 中不含符合的 resourceId 則會拒絕操作
@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
resources.resourceId("account");
resources.tokenServices(tokenServices());
}
// 配置哪些資源可以不用檢驗 Token ，這邊是對 swagger 的檔案無條件存取 及忘記密碼 passwordforget，其他的都要
@Override
public void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
http.httpBasic().disable();
http.authorizeRequests().antMatchers(
"/swagger-ui.html",
"/v2/api-docs/**",
"/swagger-resources/**",
"/webjars/**",
"/api/v1/passwordforget"
).permitAll();
// 或是也可以集中配置在這裡
//.antMatchers(HttpMethod.GET, "/my").access("#oauth2.hasScope('my-resource.read')")
http.authorizeRequests().anyRequest().fullyAuthenticated();
}
// 主要是配置 JWT 的密鑰
@Bean
public JwtAccessTokenConverter accessTokenConverter() {
JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
converter.setSigningKey("ASDFASFsdfsdfsdfsfadsf234asdfasfdas");
return converter;
}
// 配置 JwtTokenStore
@Bean
public TokenStore tokenStore() {
return new JwtTokenStore(accessTokenConverter());
}
// 配置，使用預設的 DefaultTokenServices 就可以了，因為我們這邊只是做驗證而已
@Bean
@Primary
public DefaultTokenServices tokenServices() {
DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
defaultTokenServices.setTokenStore(tokenStore());
return defaultTokenServices;
}
}
接下來就可以在 Service 這邊配置需要的權限
RoleService.java
import com.ps.dto.RoleDto;
import com.ps.model.Role;
import com.ps.repository.RoleRepository;
import org.apache.commons.lang3.RandomStringUtils;
import org.modelmapper.ModelMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Created by samchu on 2017/2/17.
*/
@Service
public class RoleService {
@Autowired
private RoleRepository roleRepository;
// 這邊需要有 role 或是 role.readonly 的操作範圍的人才可以讀取角色列表
@PreAuthorize("#oauth2.hasScope('role') or #oauth2.hasScope('role.readonly')")
public List<Role> listAll(){
return roleRepository.findAll();
}
// 這邊是寫入角色，所以限定 role 的操作範圍才可以寫入
@PreAuthorize("#oauth2.hasScope('role')")
public Role create(RoleDto roleDto) {
ModelMapper modelMapper = new ModelMapper();
Role role = modelMapper.map(roleDto, Role.class);
role.setRoleid(RandomStringUtils.randomAlphanumeric(10));
roleRepository.save(role);
return role;
}
}
像是 hasScope('role') 或是 hasScope('role.readonly') 其實都是非常簡單好讀的敘述方式
那像用到 spring-boot-starter-data-rest 的功能，你其實可以像下面這樣設定
AccountRepository.java
import com.ps.model.Account;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import org.springframework.data.rest.core.annotation.RestResource;
import org.springframework.security.access.prepost.PreAuthorize;
/**
* Created by samchu on 2017/2/9.
*/
@RepositoryRestResource
public interface AccountRepository extends JpaRepository<Account, String> {
//@RestResource(path = "findByUsername")
@Query("SELECT a FROM Account a WHERE a.username = :username")
Account findByUsername(@Param("username") String username);
// Prevents GET /accounts/:id
@Override
@RestResource(exported = true)
@PreAuthorize("#oauth2.hasScope('account')")
Account findOne(String id);
// Prevents GET /account
@Override
@RestResource(exported = false)
@PreAuthorize("#oauth2.hasScope('account')")
Page<Account> findAll(Pageable pageable);
// Prevents POST /account and PATCH /account/:id
@Override
@RestResource(exported = true)
@PreAuthorize("#oauth2.hasScope('account')")
Account save(Account s);
// Prevents DELETE /account/:id
@Override
@RestResource(exported = false)
@PreAuthorize("#oauth2.hasScope('account')")
void delete(Account t);
}
- 透過 RestResource(exported = false) 來配置此方法是否供外部透過 Rest 操作
- 特過 PreAuthorize 一樣可以設定符合操作的 scope 範圍
RestResource 預設是 exported = true，所以有的時候你自己會卡到外部內部權限問題
舉例說外部 rest 操作必須要有 account 操作範圍，但是某些時候是系統內部要操作，這時候你就沒有 token 來檢驗
不過你可以另外設定個系統操作的 Repository 像下面，這樣一來這個 Class 內部所有的方法都不對外露出，就可以放心用啦
AccountPrivateRepository.java
@Repository
@RestResource(exported = false)
public interface AccountPrivateRepository extends JpaRepository<Account, String> {
@Query("SELECT a FROM Account a WHERE a.username = :username")
Account findByUsername(@Param("username") String username);
}
啟動程式
PsAccountApplication.java
@EnableJpaAuditing
//@EnableTransactionManagement
@SpringBootApplication
public class PsAccountApplication {
public static void main(String[] args) {
SpringApplication.run(PsAccountApplication.class, args);
}
}
透過標準的 OAuth 跟 JWT 是不是省下很多自己開發的力氣呢?
使用 OAuth 不論是自用或開放兩相宜XD，使用 JWT 簡化驗證架構跟流程
雖然學習是有成本的，但是比起自己做一套授權系統，應該還是划算的很多
把力氣留在你的商業平台吧，這種基礎建設就盡量使用開源以及標準吧

数据结构与算法分析
Frank.M.Carrano / 金名 / 清华大学出版社 / 2007-11 / 98.00元
“数据结构”是计算机专业的基础与核心课程之一，Java是现今一种热门的语言。本书在编写过程中特别考虑到了面向对象程序设计（OOP）的思想与Java语言的特性。它不是从基于另一种程序设计语言的数据结构教材简单地“改编”而来的，因此在数据结构的实现上更加“地道”地运用了Java语言，并且自始至终强调以面向对象的方式来思考、分析和解决问题。 本书是为数据结构入门课程（通常课号是CS-2）而编写的教......一起来看看 《数据结构与算法分析》 这本书的介绍吧!
