WebApplicationInitializer提供了一种以编程方式表示标准web.xml文件的一部分的方法 - servlet,过滤器,监听器.

但是,我无法找到使用WebApplicationInitializer表示这些元素(会话超时,错误页面)的好方法,是否仍需要维护这些元素的web.xml？

<session-config>
    <session-timeout>30</session-timeout>
</session-config>

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/uncaughtException</location>
</error-page>

<error-page>
    <error-code>404</error-code>
    <location>/resourceNotFound</location>
</error-page>

我正在尝试使用Spring AOP和Spring MVC Controller.我有3个方面,并希望按特定顺序.为了做到这一点,我使用Ordered接口并实现getOrder方法:

@Aspect
@Component
public class LoggingAspect implements Ordered{

public int getOrder() {
System.out.println("Abra");
return 1;
}

建议课程:

@Component
@Controller
public class HomeController {   

切入点:

@Aspect
public class SystemArchitecture {

    @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
    public void inHomeController(){}

    @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
    public void loggable(){}

    @Pointcut("execution (* com.jajah.StorageManager.HomeController.*(..))")
    public void authenticated(){}

}

我已经声明了以下方面建议dao调用,我正在尝试运行@Before建议,但它不起作用.

这就是方面.

package com.hedgebenefits.aop;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
@Aspect
public class AccessControlAspect {
    @Before("within(com.hedgebenefits.daos..*) && execution(public * *(..))")
    public void daoCall() {
        System.out.println("Before advice invoked for DAO method called ");
    }
}

我的application-context.xml具有以下标记

<aop:aspectj-autoproxy/>

我的Dao课程如下:

package com.hedgebenefits.daos.impl;

import com.hedgebenefits.daos.AdminDao;
import com.hedgebenefits.domain.Admin;
import org.springframework.stereotype.Repository;

@Repository
public class AdminDaoImpl implements AdminDao{
    @Override
    public void save(Admin admin) {
    }
}

我放了一个断点,但我可以看到它不活跃,我肯定在这里做了一些愚蠢的错误,但无法搞清楚.PL.咨询.

我安装了Spring Tool Suite,现在将它用于一个小样本项目.但是我的dispatcher-servlet.xml文件中出现错误:

Build path is incomplete. Cannot find class file for org/springframework/beans/factory/Aware

此处突出显示此错误:

<bean
    **class="org.springframework.web.servlet.view.InternalResourceViewResolver">**
    <property name="prefix">
        <value>/WEB-INF/pages/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

任何想法？

这可能是一个基本的scala问题,但无法弄清楚如何:

如何使用Scala表达此java循环:

for (int i=1;i<100000;i=2*i)

我理解这是一种可能的方式:

  def loopByTwiceBefore(from:Int, to:Int)(f:Int=>Unit):Unit = {
    if (from<to){
        f(from)
        loopByTwiceBefore(from*2, to)(f);
    }
  }  

但是在Scala中是否有更规范的方法可以做到这一点.

我想使用MongoRepository接口,但我有一个BeanCreationException异常.ComponentScan和MappingBasePackage字符串已正确填充.

这是我的代码:

(Jersey类)@Component @Path("技能")公共类SkillREST {

    @Autowired
    private UserService userService;    

    @POST
    @Path("/{token}")
    @Produces({MediaType.APPLICATION_JSON})
    public List<Skill> addSkill(@PathParam("token") String token, Skill skill){
        return userService.getAllSkills();
    }
}

以下是未正确自动装配存储库的服务:

@Component
public class UserService {
    @Autowired
    SkillRepository skillRepository;

    public List<Skill> getAllSkills(){
        return skillRepository.findAll();
    }
}


@Repository
public interface SkillRepository extends MongoRepository<Skill, String> {
}

Spring配置类:

@Configuration
@PropertySource("classpath:mongodb.properties")
@EnableMongoRepositories
@ComponentScan("com.headlezz")
public class SpringMongoConfig extends AbstractMongoConfiguration {
    @Inject
    Environment environment;
    @Override
    public String getDatabaseName() {
        return environment.getProperty("db.name");
    }

    @Override
    @Bean
    public Mongo mongo() throws Exception {
        return new …
