（4）编写方法测试
MonsterService 接口：
package com.li.service;
import com.li.entity.Monster;
import java.util.List;
/**
* @author 李
* @version 1.0
*/
public interface MonsterService {
//增加方法，通过传入的名字返回 monster列表
public List<Monster> findMonsterByName(String name);
}
MonsterServiceImpl 实现类：
package com.li.service.impl;
import com.li.entity.Monster;
import com.li.myspringmvc.annotation.Service;
import com.li.service.MonsterService;
import java.util.ArrayList;
import java.util.List;
/**
* @author 李
* @version 1.0
* MonsterServiceImpl 作为一个Service对象注入容器
*/
@Service
public class MonsterServiceImpl implements MonsterService {
@Override
public List<Monster> findMonsterByName(String name) {
//这里模拟到 DB获取数据
List<Monster> monsters = new ArrayList<>();
monsters.add(new Monster(100, "牛魔王", "芭蕉扇", 400));
monsters.add(new Monster(200, "猫妖", "撕咬", 800));
monsters.add(new Monster(300, "鼠精", "偷灯油", 200));
monsters.add(new Monster(400, "大象精", "运木头", 300));
monsters.add(new Monster(500, "白骨精", "吐烟雾", 500));
//创建集合返回查询到的monster集合
List<Monster> findMonsters = new ArrayList<>();
//遍历monster集合，将符合条件的放到findMonster集合中
for (Monster monster : monsters) {
if (monster.getName().contains(name)) {
findMonsters.add(monster);
}
}
return findMonsters;
}
}
MonsterController 控制器类：
package com.li.controller;
import com.li.entity.Monster;
import com.li.myspringmvc.annotation.AutoWired;
import com.li.myspringmvc.annotation.Controller;
import com.li.myspringmvc.annotation.RequestMapping;
import com.li.myspringmvc.annotation.RequestParam;
import com.li.service.MonsterService;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
/**
* @author 李
* @version 1.0
* 用于测试的 Controller
*/
@Controller
public class MonsterController {
//属性
@AutoWired
private MonsterService monsterService;
//增加方法，通过name返回对应的monster集合
@RequestMapping(value = "/monster/find")
public void findMonsterByName(HttpServletRequest request,
HttpServletResponse response,
@RequestParam(value = "name") String monsterName) {
//设置编码
response.setContentType("text/html;charset=utf-8");
System.out.println("----接收到的name=" + monsterName);
StringBuilder content = new StringBuilder("<h1>妖怪列表信息</h1>");
content.append("<table border='1px' width='400px' style='border-collapse:collapse'>");
//调用 monsterService的方法
List<Monster> monsters = monsterService.findMonsterByName(monsterName);
for (Monster monst
