生成二维码一直报找不到EncodeHintType类

Question

用测试类启动正常，复制到项目中报错，一直提示找不到EncodeHintType类

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: com/google/zxing/EncodeHintType

pom文件添加：
        <dependency>
    <groupId>com.google.zxing</groupId>
    <artifactId>javase</artifactId>
    <version>3.1.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.zxing</groupId>
        <artifactId>core</artifactId>
        <version>3.1.0</version>
    </dependency>

异常代码是：hints.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.H);
