在tomcat服务器上部署代码时遇到问题 我已经写了下面的代码。

我的主班：

package com.indiamart.search;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SuggestMcatApplication  extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(SuggestMcatApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // TODO Auto-generated method stub
        return builder.sources(SuggestMcatApplication.class);
    }}

我的控制器类：-

package com.abc.search;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;

import org.json.JSONObject;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class serviceController {

    @RequestMapping("/suggestMcat/related_info")

    public String getSearchString(HttpServletRequest request){
        JSONObject json;
        json =  new JSONObject(request);
        return json.toString();
    }
    }

我的pom.xml

在进行战争并在tomcat服务器上部署时，出现以下错误：

请提出建议。

答案2之后，我的问题已解决，但部署与控制器有关 白标错误页面 此应用程序没有针对/ error的显式映射，因此您将其视为后备。

2 个答案:

答案 0 :(得分：0)

您的项目引用了类org.springframework.web.filter.FormContentFilter，该类自5.1版以来就存在于spring-web工件中。

因此，您将需要删除对该类的引用或添加缺少的spring-web工件。

答案 1 :(得分：0)

看来您自己建立了一个战争档案。您应该使用spring来做到这一点。

这里有完整的示例

pom.xml应该看起来像这样

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>1.5.8.RELEASE</version>
    </parent>

    <groupId>com.surasint.example</groupId>
    <artifactId>spring-boot-12</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>
    <properties>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- JSP -->

        <!-- to deploy as a war in tomcat -->

            </plugin>
        </plugins>
    </build>
</project>

关键点是：

<packaging>war</packaging>

和：

<!-- to deploy as a war in tomcat -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
