第一个地方
@RequestMapping(value = "/registershop", method = RequestMethod.POST)
@ResponseBody
private Map<String, Object> registerShop(HttpServletRequest request) {
Map<String, Object> modelMap = new HashMap<String, Object>();
if (!CodeUtil.checkVerifyCode(request)) {
// 错误返回页面
}
// ↓这里shopStr执行之后是null
String shopStr = HttpServletRequestUtil.getString(request, "shopStr");
ObjectMapper mapper = new ObjectMapper();
Shop shop = null;
try {
// ↓因为shopStr是null,所以这里也报异常
shop = mapper.readValue(shopStr, Shop.class);
} catch (Exception e) {
// 错误返回页面
}
第二个地方
public class CodeUtil {
// ↓检查验证码是否和预期相符
public static boolean checkVerifyCode(HttpServletRequest request) {
String verifyCodeExpected = (String) request.getSession()
.getAttribute(com.google.code.kaptcha.Constants.KAPTCHA_SESSION_KEY);
// ↓这里获取是空,所以验证码一直报错
String verifyCodeActual = HttpServletRequestUtil.getString(request, "verifyCodeActual");
// ↓用原来的获取方法也是空的
// String verifyCodeActual = (String) request.getParameter("verifyCodeActual");
if (verifyCodeActual == null || !verifyCodeActual.equals(verifyCodeExpected)) {
return false;
}
return true;
}
}

按照老师给的代码,自己看了一下,做了两个改动,代码测试成功了。
但是我不知道是哪个影响的。
spring-web.xml
```xml
<!-- 3.定义视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/html/"></property>
<property name="suffix" value=".html"></property>
</bean>
<!-- 文件上传解析器 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"></property>
<!-- 1024 * 1024 * 20 = 20M -->
<property name="maxUploadSize" value="20971520"></property>
<property name="maxInMemorySize" value="20971520"></property>
</bean>
```
> 第三个这里多了一个文件上传解析器,之前跟着老师敲得代码,也不知道为什么这里少了这个。
2.pom.xml
在插件那一块,我原来得代码
```xml
<plugins>
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>3.1.0</version>
</plugin>
<!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging -->

<plugin>
<artifactId>maven-deploy-plugin</artifactId>

```
老师得代码
```xml

</configuration>
</plugin>
</plugins>
```
> 因为我是使用IDEA自己新建得Maven项目,所以这里IDEA帮我加的,当时我以为这里官方应该加的应该没什么问题,所以就没管了。现在改过来就好了
感觉是spring-web.xml或者import的request类型弄错了?可以直接复制粘贴我的ok的例子,没问题后,看看那差距在哪里
