我有以下代码,并希望使用lambda函数实现它只是为了好玩.可以使用基本的聚合操作吗？

List<Integer> result = new ArrayList<>();

for (int i = 1; i <= 10; i++) {
    if (10 % i == 0) {
        result.add(i);
        if (i != 5) {
            result.add(10 / i);
        }
    }
}

使用lambda:

List<Integer> result = IntStream.rangeClosed(1, 10)
                                .boxed()
                                .filter(i -> 10 % i == 0)
                                // a map or forEach function here?
                                // .map(return 10 / i -> if i != 5)
                                .collect(Collectors.toList());

当我启动springboot应用程序时,我的SpringBootLoginController类抛出此错误(无法启动嵌入式容器),如下所示.它是一个hello world类型的spring启动应用程序示例.

我正在尝试使用 Spring Security 来连接 LDAP，但它总是显示错误的凭据问题。
我想我的代码可能有问题：

@Configuration\n@EnableWebSecurity\n@EnableGlobalMethodSecurity(prePostEnabled = true)\npublic class SecurityConfig extends WebSecurityConfigurerAdapter {\n    @Override\n    public void configure(WebSecurity web) throws Exception {\n        web.debug(true);\n    }\n    @Autowired\n    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {\n\n        auth.ldapAuthentication().userDnPatterns("sAMAccountName={0},OU=SupportUsers,OU=Users,OU=company,DC=ad,DC=company,DC=com,DC=pl")\n            .contextSource(contextSource()).passwordCompare().passwordAttribute("userPassword");\n    }\n    protected void configure(HttpSecurity http) throws Exception {\n        http\n            .authorizeRequests()\n                .anyRequest().fullyAuthenticated()\n                .and()\n            .formLogin();\n        http.csrf().disable(); //Vaadin already have built in csrf\n    }\n    @Bean\n    public LdapContextSource contextSource () {\n        LdapContextSource contextSource= new LdapContextSource();\n        contextSource.setUrl("ldap://192.168.2.2:389");\n        contextSource.setBase("dc=ad,dc=company,dc=com,dc=pl");\n        contextSource.setUserDn("CN=lister,OU=SupportUsers,OU=Users,OU=company,DC=ad,DC=company,DC=com,DC=pl");\n        contextSource.setPassword("examplePassword");\n        contextSource.setAnonymousReadOnly(false);\n        contextSource.setPooled(true);\n        contextSource.afterPropertiesSet();\n        return contextSource;\n    }\n}\n

我在代码中找不到错误，也许我做错了事情。这是我的 pom.xml：
