spring boot java springboot权限系统

要实现一个完整的权限系统，需要考虑以下几个方面： 1.用户认证和授权：用户登录后需要验证其身份，并根据其角色和权限来授予访问系统资源的权限。 2.资源管理：需要对系统资源进行管理，包括增加、删除、修改和查询资源。 3.角色管理：需要定义不同的角色，每个角色可以访问的资源不同。 4.权限管理：需要为每个角色分配不同的权限，以控制其对资源的访问。（1）用户认证和授权使用Spring Security框架实现用户认证和授权，可以通过配置用户角色和权限来控制访问资源。可以使用数据库存储用户、角色和权限信息。（2）资源管理可以使用数据库存储资源信息，并使用RESTful API暴露资源的增加、删除、修改和查询接口。使用Spring Data JPA和Hibernate来操作数据库。（3）角色管理可以使用数据库存储角色信息，并使用RESTful API暴露角色的增加、删除、修改和查询接口。同样使用Spring Data JPA和Hibernate来操作数据库。（4）权限管理可以使用数据库存储权限信息，并使用RESTful API暴露权限的增加、删除、修改和查询接口。同样使用Spring Data JPA和Hibernate来操作数据库。

1）用户认证和授权使用Spring Security框架实现用户认证和授权，可以使用JWT令牌作为认证机制。可以使用数据库存储用户、角色和权限信息，例如使用MySQL数据库。

@Configuration

@EnableWebSecurity

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired

private UserDetailsServiceImpl userDetailsService;

@Autowired

private JwtAuthenticationEntryPoint jwtAuthenticationEntryPoint;

@Autowired

private JwtRequestFilter jwtRequestFilter;

@Autowired

public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());

}

@Bean

public PasswordEncoder passwordEncoder() {

return new BCryptPasswordEncoder();

}

@Bean

@Override

public AuthenticationManager authenticationManagerBean() throws Exception {

return super.authenticationManagerBean();

}

@Override

protected void configure(HttpSecurity httpSecurity) throws Exception {

httpSecurity.csrf().disable()

.authorizeRequests().antMatchers("/authenticate").permitAll().

anyRequest().authenticated().and().

exceptionHandling().authenticationEntryPoint(jwtAuthenticationEntryPoint).and().sessionManagement()

.sessionCreationPolicy(SessionCreationPolicy.STATELESS);

httpSecurity.addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class);

}

2）资源管理使用MySQL数据库存储资源信息，并使用RESTful API暴露资源的增加、删除、修改和查询接口。

@RestController

@RequestMapping("/api/resource")

public class ResourceController {

@Autowired

private ResourceService resourceService;

@PostMapping

public ResponseEntity createResource(@RequestBody Resource resource) {

Resource createdResource = resourceService.createResource(resource);

return new ResponseEntity<>(createdResource, HttpStatus.CREATED);

}

@GetMapping("/{id}")

public ResponseEntity getResourceById(@PathVariable Long id) {

Resource resource = resourceService.getResourceById(id);

return new ResponseEntity<>(resource, HttpStatus.OK);

}

@PutMapping("/{id}")

public ResponseEntity updateResource(@PathVariable Long id, @RequestBody Resource resource) {

Resource updatedResource = resourceService.updateResource(id, resource);

return new ResponseEntity<>(updatedResource, HttpStatus.OK);

}

@DeleteMapping("/{id}")

public ResponseEntity deleteResource(@PathVariable Long id) {

resourceService.deleteResource(id);

return new ResponseEntity<>(HttpStatus.NO_CONTENT);

}

@GetMapping

public ResponseEntity> getAllResources() {

List resources = resourceService.getAllResources();

return new ResponseEntity<>(resources, HttpStatus.OK);

}

3）角色管理

使用MySQL数据库存储角色信息，并使用RESTful API暴露角色的增加、删除、修改和查询接口。

@RestController

@RequestMapping("/api/role")

public class RoleController {

@Autowired

private RoleService roleService;

@PostMapping

public ResponseEntity createRole(@RequestBody Role role) {

Role createdRole = roleService.createRole(role);

return new ResponseEntity<>(createdRole, HttpStatus.CREATED);

}

@GetMapping("/{id}")

public ResponseEntity getRoleById(@PathVariable Long id) {

Role role = roleService.getRoleById(id);

return new ResponseEntity<>(role, HttpStatus.OK);

}

@PutMapping("/{id}")

public ResponseEntity updateRole(@PathVariable Long id, @RequestBody Role role) {

Role updatedRole = roleService.updateRole(id, role);

return new ResponseEntity<>(updatedRole, HttpStatus.OK);

}

@DeleteMapping("/{id}")

public ResponseEntity deleteRole(@PathVariable Long id) {

roleService.deleteRole(id);

return new ResponseEntity<>(HttpStatus.NO_CONTENT);

}

@GetMapping

public ResponseEntity> getAllRoles() {

List roles = roleService.getAllRoles();

return new ResponseEntity<>(roles, HttpStatus.OK);

}

4）权限管理使用MySQL数据库存储权限信息，并使用RESTful API暴露权限的增加、删除、修改和查询接口。

@RestController

@RequestMapping("/api/permission")

public class PermissionController {

@Autowired

private PermissionService permissionService;

@PostMapping

public ResponseEntity createPermission(@RequestBody Permission permission) {

Permission createdPermission = permissionService.createPermission(permission);

return new ResponseEntity<>(createdPermission, HttpStatus.CREATED);

}

@GetMapping("/{id}")

public ResponseEntity getPermissionById(@PathVariable Long id) {

Permission permission = permissionService.getPermissionById(id);

return new ResponseEntity<>(permission, HttpStatus.OK);

}

@PutMapping("/{id}")

public ResponseEntity updatePermission(@PathVariable Long id, @RequestBody Permission permission) {

Permission updatedPermission = permissionService.updatePermission(id, permission);

return new ResponseEntity<>(updatedPermission, HttpStatus.OK);

}

@DeleteMapping("/{id}")

public ResponseEntity deletePermission(@PathVariable Long id) {

permissionService.deletePermission(id);

return new ResponseEntity<>(HttpStatus.NO_CONTENT);

}

@GetMapping

public ResponseEntity> getAllPermissions() {

List permissions = permissionService.getAllPermissions();

return new ResponseEntity<>(permissions, HttpStatus.OK);

}

5）用户管理

使用MySQL数据库存储用户信息，并使用RESTful API暴露用户的增加、删除、修改和查询接口。

@RestController

@RequestMapping("/api/user")

public class UserController {

@Autowired

private UserService userService;

@PostMapping

public ResponseEntity createUser(@RequestBody User user) {

User createdUser = userService.createUser(user);

return new ResponseEntity<>(createdUser, HttpStatus.CREATED);

}

@GetMapping("/{id}")

public ResponseEntity getUserById(@PathVariable Long id) {

User user = userService.getUserById(id);

return new ResponseEntity<>(user, HttpStatus.OK);

}

@PutMapping("/{id}")

public ResponseEntity updateUser(@PathVariable Long id, @RequestBody User user) {

User updatedUser = userService.updateUser(id, user);

return new ResponseEntity<>(updatedUser, HttpStatus.OK);

}

@DeleteMapping("/{id}")

public ResponseEntity deleteUser(@PathVariable Long id) {

userService.deleteUser(id);

return new ResponseEntity<>(HttpStatus.NO_CONTENT);

}

@GetMapping

public ResponseEntity> getAllUsers() {

List users = userService.getAllUsers();

return new ResponseEntity<>(users, HttpStatus.OK);

}

6）权限控制使用Spring Security实现基于角色的访问控制，根据用户的角色授予或拒绝访问。

@Configuration

@EnableWebSecurity

public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired

private CustomUserDetailsService userDetailsService;

@Override

protected void configure(HttpSecurity http) throws Exception {

http.authorizeRequests()

.antMatchers("/api/**").authenticated()

.and()

.formLogin()

.and()

.httpBasic()

.and()

.csrf().disable();

}

@Autowired

public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());

}

@Bean

public PasswordEncoder passwordEncoder() {

return new BCryptPasswordEncoder();

}

以上是一个基本的权限系统实现，可以根据具体业务需求进行修改和扩展。
