我的公司正在从tomcat迁移到WebLogic 12.1.3，所以我试图在WebLogic上创建一个示例Spring MVC rest应用程序。 我从这里https://github.com/hasanozgan/spring-mvc-akka-maven-weblogic-demo克隆了一个示例项目，该项目工作正常，然后相应地修改了几个文件。
POM 将spring版本更改为4.2.1.RELEASE 添加Jackson依赖项

mvc-dispatcher-servlet.xml 因为它是一个剩余应用程序，所以对InternalResourceViewResolver进行了评论。
<beans xmlns="http://www.springframework.org/schema/beans"

带有3个变量的示例数据pojo类。
package com.hasanozgan.demo.controllers;
import java.util.Date;
public class Data {
int rollNo;
String name;
Date d;
public int getRollNo() {
return rollNo;
}
public void setRollNo(int rollNo) {
this.rollNo = rollNo;
}
public Date getD() {
return d;
}
public void setD(Date d) {
this.d = d;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
控制器 用@RestController替换@Controller并添加pojo类作为返回类型
package com.hasanozgan.demo.controllers;
import java.util.Date;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.hasanozgan.demo.controllers.Data;
@RestController
@RequestMapping("/")
public class HelloController {
@RequestMapping(method = RequestMethod.GET)
public Data home() {
Data d = new Data();
d.setName("hello");
d.setRollNo(1);
d.setD(new Date());
return d;
}
}
在weblogic上部署成功，但是当我点击rest url
Root cause of ServletException.
java.lang.StackOverflowError

我在做什么错了？
