解决方案：
PasswordEncoder
@Throws(Exception::class)
override fun configure(auth: AuthenticationManagerBuilder) {
//AuthenticationManager 使用我们的 lightSwordUserDetailService 来获取用户信息
auth.userDetailsService(userDetailsService())
.passwordEncoder(passwordEncoder())
}
/**
* 密码加密算法
*
* @return
*/
@Bean
fun passwordEncoder(): BCryptPasswordEncoder {
return BCryptPasswordEncoder();
}
MyUserDetailService.kt
package com.ksb.ksb_with_security.service
import com.ksb.ksb_with_security.dao.UserDao
import org.slf4j.LoggerFactory
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.security.core.authority.SimpleGrantedAuthority
import org.springframework.security.core.userdetails.UserDetails
import org.springframework.security.core.userdetails.UserDetailsService
import org.springframework.security.core.userdetails.UsernameNotFoundException
import org.springframework.stereotype.Service
@Service
class MyUserDetailService : UserDetailsService {
val logger = LoggerFactory.getLogger(MyUserDetailService::class.java)
@Autowired lateinit var userDao: UserDao
override fun loadUserByUsername(username: String): UserDetails {
val user = userDao.findByUsername(username) ?: throw UsernameNotFoundException(username + " not found")
logger.info("user = {}", user)
val roles = user.roles
val authorities = mutableSetOf<SimpleGrantedAuthority>()
roles.forEach {
authorities.add(SimpleGrantedAuthority(it.role))
}
return org.springframework.security.core.userdetails.User( // 此处为了区分我们本地系统中的 User 实体类，特意列出userdetails 的 User 类的全路径
username,
user.password,
authorities
)
}
}
Spring Boot 应用启动，数据库初始化用户权限数据：
package com.ksb.ksb_with_security
import com.ksb.ksb_with_security.dao.RoleDao
import com.ksb.ksb_with_security.dao.UserDao
import com.ksb.ksb_with_security.entity.Role
import com.ksb.ksb_with_security.entity.User
import org.springframework.boot.ApplicationRunner
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.builder.SpringApplicationBuilder
import org.springframework.context.support.beans
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder
@SpringBootApplication
class KsbWithSecurityApplication
fun main(args: Array<String>) {
SpringApplicationBuilder().initializers(
beans {
bean {
ApplicationRunner {
try {
val roleDao = ref<RoleDao>()
// 普通用户角色
val roleUser = Role()
roleUser.role = "ROLE_USER"
val r1 = roleDao.save(roleUser)
// 超级管理员角色
val roleAdmin = Role()
roleAdmin.role = "ROLE_ADMIN"
val r2 = roleDao.save(roleAdmin)
val userDao = ref<UserDao>()
// 普通用户
val user = User()
user.username = "user"
user.password = BCryptPasswordEncoder().encode("user")
val userRoles = setOf(r1)
user.roles = userRoles
userDao.save(user)
// 超级管理员用户
val admin = User()
admin.username = "admin"
admin.password = BCryptPasswordEncoder().encode("admin")
val adminRoles = setOf(r1, r2)
admin.roles = adminRoles
userDao.save(admin)
} catch (e: Exception) {
e.printStackTrace()
}
}
}
}
).sources(KsbWithSecurityApplication::class.java).run(*args)
}
