## 错误 3


### 3.1 错误原因


错误是 SpringBoot 没有扫描的 CurrencyMapper


### 3.2 解决方法


在 SpringBoot 启动类中添加 @MapperScan(basePackages = {“com.xu.erp.\*\*.mapper\*”})

package com.xu.erp;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan(basePackages = {“com.xu.erp.**.mapper*”})
@SpringBootApplication
public class Application {

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

}


### 3.3 错误信息

package com.xu.erp;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan(basePackages = {“com.xu.erp.mapper”,“com.xu.erp.service.impl”})
@SpringBootApplication
public class Application {

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

}

## 错误4


### 4.1 错误原因

@RequestMapping(“/test”)
public Object test() {
return service.all();
}


使用 @Controller 时没有在对应的方法上使用 @ResponseBody SpringBoot 会将返回的数据当成一个新的请求。


### 4.2 解决方法


1 将 @Controller 换成 @ResetController。  
 2 在对应的方法上面增加 @ResponseBody。


### 4.3 错误信息

## 错误5


### 5.1 错误原因


在使用 mybatis-plus 自动代码生成的时候 xml 开启了 二级缓存

<?xml version="1.0" encoding="UTF-8"?>

<!-- 开启二级缓存 -->
<cache type="org.mybatis.caches.ehcache.LoggingEhcache"/>

<!-- 通用查询映射结果 -->
<resultMap id="BaseResultMap" type="com.xu.erp.entity.Currency">
	<id column="id" property="id" />
	<result column="tag" property="tag" />
	<result column="name" property="name" />
</resultMap>

<!-- 通用查询结果列 -->
<sql id="Base\_Column\_List">
    id, tag, name
</sql>


### 5.2 解决方法


删除 二级缓存
