使用jackson核心流式API的java.lang.NoSuchMethodError[重复]

Question

我使用的是jackson核心版本2.8.3，但为什么我一直得到java.lang.nosuchmethoderror？我没有使用任何其他jackson的模块，只是核心（流）API

Object[] result = imageGenerator.generate(lowerBound, upperBound, fileNames);
MWNumericArray array = (MWNumericArray)result[0];
try (Writer writer = response.getWriter();
     JsonGenerator generator = res.getJsonFactory().createGenerator(writer)) {

     generator.writeStartObject();
         generator.writeFieldName("dimension");
         generator.writeArray(array.getDimensions(), 0, 2); // java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonGenerator.writeArray([III)V

         int[] pixels = array.getIntData();
         generator.writeFieldName("pixels");
         generator.writeArray(pixels, 0, pixels.length);
     generator.writeEndObject();
}

Answer 1

这个错误几乎总是（99%的情况）表明您根据一个库版本构建代码，但部署环境有一个不同的版本，该版本缺少该方法。代码编译正确，但当加载到部署环境中时，JVM试图将其与可用的库类版本链接，但找不到该方法。

解决方案是确保在开发环境和部署服务器中都有相同版本的库。
