Spring boot :在自定义UserDetailsService中自动装配authenticationManager时，delegateBuilder不能为空
Spring boot :在自定义UserDetailsService中自动装配authenticationManager时，delegateBuilder不能为空
提问于 2018-12-19 16:14:49
您好，我是spring boot新手，正在尝试将安全性实现到我的rest中。
我使用的是spring boot 2.0.7.release
我已经将我的WebSecurityConfig配置如下
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Resource(name = "userService")
private UserDetailsService userDetailsService;
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Autowired
public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(encoder());
}
@Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
return new JwtAuthenticationFilter();
}
@Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
....
}我已经添加了资源名称，这样我就可以指向自定义userDetailsService。
我已经尝试通过来配置authenticationManager Bean，并通过限定符authenticationManager bean指向bean，但它仍然错误不变。
我的pom.xml看起来像是为了安全
......
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
......我实现的UserServiceImpl是
@Service(value = "userService")
public class UserServiceImpl implements UserService, UserDetailsService {
@Autowired
private UserDAOService userDao;
@Autowired
private AuthenticationManager authenticationManager;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userDao.findByUsername(username);
if(user == null){
throw new UsernameNotFoundException("Invalid username or password.");
}
return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), getAuthority());
}
@Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}以下是错误日志。我只提供了邮件错误

为了更好地帮助您，最好指明您正在遵循哪个参考来实现JWT mechansim。
从概念上讲，这部分源代码是错误的：
@Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}看看下面的修改是否对您有帮助
1)考虑使用Java Config在单独的配置类中声明bean
@Configuration
public class ServiceConfig{
@Bean
protected UserDAOService daoService()
{
return new UserDAOServiceImpl();
}
@Bean
protected UserDetailsService userDetailService( UserDAOService dao )
{
return new UserServiceImpl( dao );
}
@Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
@Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception{ {
return new JwtAuthenticationFilter();
}
}2)修改您的WebSecurityConfig
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private PasswordEncoder passwordEncoder;
@Override
protected void configure( AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService( userDetailsService ).passwordEncoder( passwordEncoder );
}
