问题遇到的现象和发生背景
使用FreeMaker开发Springboot项目失败,按照网上的教程进行的操作。
问题相关代码,请勿粘贴截图
如下为main.java
package org.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class main {
public static void main(String[] args) {
SpringApplication.run(main.class, args);
}
}
如下为FreemarkerIndexController.java
package org.example.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
@Controller
public class FreemarkerIndexController {
@RequestMapping("/1")
public String freemarkerIndex(Map<String, String> result){
result.put("name","Demo");
return "freemakerIndex";
}
}
如下为pom.xml
