Question

这就是我正在做的事情。

部署此应用程序在jboss中失败，因为它在tomcat中部署并且像魅力一样工作。

我正在使用eclipse的动态Web应用程序作为项目源。

将项目导出到war文件并在jboss服务器中部署也无法正常工作。

的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/api/*</url-pattern>
  </servlet-mapping>

</web-app>

弹簧servlet.xml中：

 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:mvc="http://www.springframework.org/schema/mvc"  xmlns:context="http://www.springframework.org/schema/context"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="
       http://www.springframework.org/schema/beans

       http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.sixdee.engrafi.bl" />

</beans>

控制器：

package com.sixdee.engrafi.bl;

import org.apache.log4j.Logger;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class AnotherTest {

    static Logger logger = Logger.getLogger(AnotherTest.class);
    @RequestMapping(produces=MediaType.APPLICATION_JSON_VALUE,value="/ahi")
    @ResponseBody

    public String test(String[] args) {
        logger.debug("logging");
        System.out.println("Hello"); 
        String message = "{\"a\":\"b\"}";
        return message;
    }

}

和JBOSS中的错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/exc/InvalidDefinitionException

Answer 1

添加maven版杰克逊，如下所示

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.4</version>
</dependency>

Spring应用程序无法在JBOSS中运行，但可以与Tomcat一起使用
