添加MyBatis代码配置并修改以下部分：

1. 添加MyBatis配置文件`MyBatisConfig`：javapackage myshop.config;

import java.util.Properties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import com.g...

2. 在`MyBatisConfig`中注入MyBatis配置属性：java@Configurationpublic class MyBatisConfig { @Bean public Properties myBatisProperties() { Properties props=new Properties(); // 添加MyBatis配置属性 return props; }}

添加MyBatis的代码并修改以下部分:

1.添加MyBatisConfig

package myshop.config; import java.util.Properties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import com.github.pagehelper.PageHelper; @Configuration public class MyBatisConfig { @Bean public PageHelper pageHelper() { System.out.println("Use PageHelper"); PageHelper pageHelper = new PageHelper(); Properties p = new Properties(); p.setProperty("offsetAsPageNum", "true"); p.setProperty("rowBoundsWithCount", "true"); p.setProperty("reasonable", "true"); pageHelper.setProperties(p); return pageHelper; } }

2.修改MyBatisController

package myshop.controller; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.github.pagehelper.PageHelper; import myshop.bean.UserInfo; import myshop.service.MyBatisService; @RestController public class MyBatisController { @Autowired private MyBatisService myBatisService; @RequestMapping("likeName") public List<UserInfo> likeName(String username) { PageHelper.startPage(1,2); return myBatisService.likeName(username); } }

3.访问地址

localhost:8080/likeName?username=天恒
