java - Spring boot @ExceptionHandler 未到达

Question

我正在研究 Spring Boot 应用程序的异常处理。我创建了自己的 Exception 类，我正在抛出，一切正常，我在控制台中收到异常，但无法到达我的 @ExceptionHandler 方法。

我的类抛出异常:

@Override
public AuctionBody insertNewAuction(AuctionBody auctionBody, int ownerId, String AUCTION_TYPE) {
    try {
        SimpleJdbcInsert simpleJdbcInsert = new SimpleJdbcInsert(dataSource).withTableName("auctions")
                .usingGeneratedKeyColumns("id");
        Map<String, Object> parameters = new HashMap<String, Object>();
        parameters.put("title", auctionBody.getTitle());
        parameters.put("type", auctionBody.getType());
        parameters.put("start_time", Timestamp.valueOf(auctionBody.getStartDate()));
        parameters.put("end_time", Timestamp.valueOf(auctionBody.getEndDate()));
        parameters.put("quantity", auctionBody.getItemQuantity());
        parameters.put("starting_price", auctionBody.getStartingPrice());
        parameters.put("currency", auctionBody.getCurrency());
        parameters.put("status", auctionBody.getStatus());
        parameters.put("description", null);
        parameters.put("allow_bid_for_quantity", auctionBody.isAllowToBidForQuantity());
        parameters.put("buy_out_price", auctionBody.getBuyOutPrice());
        parameters.put("owner_id", ownerId);
        parameters.put("buy_out_price", auctionBody.getBuyOutPrice());
        parameters.put("quantity_left", auctionBody.getItemQuantity());
        parameters.put("uuid", auctionBody.getAuctionIdUrlOwner());
        parameters.put("allow_buy_out", auctionBody.isAllowBuyOut());
        parameters.put("link", auctionBody.getLink());
        auctionBody.setId((Integer) simpleJdbcInsert.executeAndReturnKey(parameters));


        insertNewAuctionPictures(auctionBody, auctionBody.getId());
        if (AUCTION_TYPE.equals("FullAuction")) {
            insertPeopleToInvite(auctionBody);
        }

        return auctionBody;
    }catch (DataAccessException e){
        throw new JdbcExceptions("Cant add auction");
    }
}

由于描述为空而引发异常(我这样做只是为了检查是否会到达我创建的异常处理程序)。

Exception 类如下所示:

public class JdbcExceptions extends RuntimeException {
public JdbcExceptions(String message) {
    super(message);
}

}

异常处理 Controller 类如下所示:

@ControllerAdvice
public class ExceptionHandlingController {

    @ExceptionHandler(JdbcExceptions.class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public String getJdbcException(JdbcExceptions ex){
        return "redirect:/html/errorPage";
    }
}

我知道它应该可以工作，并且我确信我有某种错误的配置，导致我的 @ExceptionHandler 无法访问，但我还没有找到答案。 此外，ExceptionHandlingController 类是在应用程序运行时创建的。

主类:

package com.visma.seli;

import com.visma.seli.config.properties.repository.DatabaseProperties;
import com.visma.seli.config.properties.repository.RepositoryProperties;
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.servlet.DispatcherServlet;

@SpringBootApplication
@EnableConfigurationProperties({RepositoryProperties.class, DatabaseProperties.class})
@EnableScheduling
@ComponentScan()
@EnableAutoConfiguration
public class SeliApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(SeliApplication.class, args);
        DispatcherServlet dispatcherServlet = (DispatcherServlet)ctx.getBean("dispatcherServlet");
        dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.bannerMode(Banner.Mode.OFF).sources(SeliApplication.class);
    }

    @Override
    protected SpringApplicationBuilder createSpringApplicationBuilder() {
        return new SpringApplicationBuilder().bannerMode(Banner.Mode.OFF);
    }
}

我的应用程序中没有其他异常处理程序，抛出后我收到我设置的消息无法添加拍卖

您可以尝试将@EnableWebMvc添加到您的配置文件

 @Configuration
 @EnableWebMvc
 @ComponentScan(...)
 public class MyAppConfiguration {

 }
