kaptcha生成驗證碼

Maven配置

<dependency>

<groupId>com.baomidou</groupId>

<artifactId>kaptcha-spring-boot-starter</artifactId>

<version>1.1.0</version>

</dependency>

如果同時引用了jcaptcha，可能會版本沖突，是以要忽略沖突包

<dependency>

<groupId>com.octo.captcha</groupId>

<artifactId>jcaptcha</artifactId>

<version>1.0</version>

<exclusions>

<exclusion>

<groupId>com.jhlabs</groupId>

<artifactId>imaging</artifactId>

</exclusion>

</exclusions>

</dependency>

建立KCaptchaController進行生成與調用驗證

package com.bruce.mall.portal.web.controller;

import com.baomidou.kaptcha.Kaptcha;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

@RestController

@RequestMapping("/kaptcha")

public class KCaptchaController {

@Autowired

    private Kaptchakaptcha;

@RequestMapping("/generatorCode")

public void generatorCode(HttpServletRequest request, HttpServletResponse response) {

kaptcha.render();

}

@GetMapping("/verify")

public String verify(String verifyCode, HttpServletRequest request) {

boolean flag =kaptcha.validate(verifyCode);

if (flag) {

return "驗證碼校驗驗通過";

}

return "驗證碼校驗不通過";

}

}
