java - 创建名称为 'securityConfig' 的 bean 时出错， Autowiring 依赖项注入(inject)失败；异常 java.lang.IllegalArgumentException

Question

我正在做图书馆管理系统的 spring boot 安全应用。当我运行我的应用程序时，出现上述错误。有人可以帮帮我吗？提前致谢!

//安全配置

@Configuration
@EnableWebSecurity
public class SecurityConfiguration  extends WebSecurityConfigurerAdapter{
    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    @Autowired
    private DataSource dataSource;
    @Value("${spring.queries.users-query}")
    private String usersQuery;
    @Value("${spring.queries.roles-query}")
    private String rolesQuery;
    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.
            jdbcAuthentication()
            .usersByUsernameQuery(usersQuery)
            .authoritiesByUsernameQuery(rolesQuery)
            .dataSource(dataSource)
                .passwordEncoder(bCryptPasswordEncoder);
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.
            authorizeRequests()
            .antMatchers("/").permitAll()
            .antMatchers("/login").permitAll()
            .antMatchers("/registration").permitAll()
            .antMatchers("/admin/**").hasAuthority("ADMIN").anyRequest()
            .authenticated().and().csrf().disable().formLogin()
            .loginPage("/login").failureUrl("/login?error=true")
            .defaultSuccessUrl("/admin/home")
            .usernameParameter("email")
            .passwordParameter("password")
            .and().logout()
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
            .logoutSuccessUrl("/").and().exceptionHandling()
            .accessDeniedPage("/access-denied");
    }
    @Override
    public void configure(WebSecurity web) throws Exception {
        web
           .ignoring()
           .antMatchers("/resources/**", "/static/**", "/css/**", "/js/**", "/images/**");
    }
}

//服务实现

@Service
public class StudentServiceImpl implements StudentService {
    private StudentRepository stuRepository;
    public StudentServiceImpl(StudentRepository stuRepository) {
        this.stuRepository=stuRepository;
    }
    @Autowired   
    private BCryptPasswordEncoder bCryptPasswordEncoder;        
    @Override
    public Student findStudentByEmail(String email) {
        return stuRepository.findByEmail(email);
    }
    @Override
    public void saveStudent(Student stu) {
        stu.setPassword(bCryptPasswordEncoder.encode(stu.getPassword()));
        stuRepository.save(stu);
    }
}

//错误

//如果我在属性文件中添加查询。我收到这个错误

Answer 1

如果您阅读错误消息，您可以看到

Could not resolve placeholder 'spring.queries.users-query' in value "${spring.queries.users-query}"

您在属性文件 spring.queries.users-query 中遗漏了一个属性添加它，错误应该消失

更新:

如果您阅读了新的错误消息:

java.lang.NoSuchMethodError: javax.persistence.PersistenceContext.synchronization()Ljavax/persistence/SynchronizationType;

您可以看到一个异常，显示不兼容的 jar 文件
