java.lang.NoSuchMethodError Using Hymanson Core Streaming API
提问by Teedeez
I am using Hymanson Core version 2.8.3, but why do I keep getting java.lang.NoSuchMethodError? I am not using any other Hymanson's modules, just the core (streaming) API
我使用的是 Hymanson Core 版本 2.8.3，但为什么我一直收到java.lang.NoSuchMethodError？我没有使用任何其他 Hymanson 的模块，只是使用核心（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.Hymanson.core.JsonGenerator.writeArray([III)V
int[] pixels = array.getIntData();
generator.writeFieldName("pixels");
generator.writeArray(pixels, 0, pixels.length);
generator.writeEndObject();
}

回答by Jim Garrison
This error almost always (99% of the time) indicates that you built your code against one library version but the deployment environment has a different version that is missing that method. Your code compiled correctly but when loaded in your deployment environment the JVM tried to link it with the version of the library class it has available and couldn't find the method.
此错误几乎总是（99% 的时间）表明您针对一个库版本构建了代码，但部署环境的另一个版本缺少该方法。您的代码编译正确，但在部署环境中加载时，JVM 尝试将其与可用的库类版本链接，但找不到该方法。
The solution is to make sure you have the same version of the library in both your development environment and your deployment server.
解决方案是确保您在开发环境和部署服务器中拥有相同版本的库。
