我的vaadin v24项目在测试模式下运行良好。部署的WAR未在Tomcat上启动。
报告以下错误：
“无法调用'com.vaadin.flow.di.Lookup.lookup（java.lang.Class）'，因为'lookup'为null”
我正在使用JPA实现登录安全性。我在网上没有找到任何关于这个问题的信息。
如何解决这个问题？
安全配置：
@EnableWebSecurity
@Configuration
public class SecurityConfiguration extends VaadinWebSecurity {
public static final String LOGOUT_URL = "/";
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeHttpRequests()
.requestMatchers("/images/*.png").permitAll();
super.configure(http);
setLoginView(http, LoginView.class, LOGOUT_URL);
}
}字符串
应用类：
@SpringBootApplication
@EnableJpaRepositories("com.tools.dimcontrol.data.repository")
@Theme(value = "dimcontrol")
public class Application extends SpringBootServletInitializer implements AppShellConfigurator {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
@Bean
SqlDataSourceScriptDatabaseInitializer dataSourceScriptDatabaseInitializer(DataSource dataSource,
SqlInitializationProperties properties, UserRepository repository) {
// This bean ensures the database is only initialized when empty
return new SqlDataSourceScriptDatabaseInitializer(dataSource, properties) {
@Override
public boolean initializeDatabase() {
if (repository.count() == 0L) {
return super.initializeDatabase();
}
return false;
}
};
}
}型

我也犯了同样的错误。只需升级到Vaadin 24.1.1和Sping Boot 3.1.1就可以解决这个问题
