kaptcha验证码图片不显示

Question

查看了其他问题，依然找不到解决方法，web.xml是和老师的代码一样的，是哪里路径出了问题呢？

shopoperation.html

common.js

pom.xml

点击更换图片会报出第三条错误

同学好，需要看看

1. 对应的jar有没有引入

2. 1 2 3 4 5 6

   <!-- https://mvnrepository.com/artifact/com.github.penggle/kaptcha --> <dependency>     <groupId>com.github.penggle</groupId>     <artifactId>kaptcha</artifactId>     <version>2.3.2</version> </dependency>

2.web.xml可以直接复制粘贴试试

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76

  老师，这俩问题都不存在，还是不显示

• 翔仔 回复 提问者 qq_高冷_6 #2

  同学好，点击切换图片，也就是验证码那个栏的地方看看，能否触发验证码更换。如果不行，我看同学截图里面还有getshopinitinfo也是404，感觉是路由路径配置不正确？先保证getshopinitinfo能够获取到店铺的区域信息、店铺类别这些，再来看看这个问题，也许就迎刃而解了，因为我这边信息不足，看到的就是404，404就是主要缺少jar或者路径配置错误导致的

  老师，点击图片也会报错（在问题中贴出来了），还有getshopinitinfo也查找了很多相关问题做了尝试，都得不到解决
