Jackson 2.6.0 正式发布，此版本主要有以下更新： #137: Allow filtering content read via `JsonParser` by specifying `JsonPointer`; uses new class `com.fasterxml.jackson.core.filter.FilteringParserDelegate` (and related, `TokenFilter`) #177: Add a check so `JsonGenerator.writeString()` won't work if `writeFieldName()` expected. #182: Inconsistent TextBuffer#getTextBuffer behavior (contributed by Masaru H) #185: Allow filtering content written via `JsonGenerator` by specifying `JsonPointer`; uses new class `com.fasterxml.jackson.core.filter.FilteringGeneratorDelegate` (and related, `TokenFilter`) #188: `JsonParser.getValueAsString()` should return field name for `JsonToken.FIELD_NAME`, not `null` #189: Add `JsonFactory.Feature.USE_THREAD_LOCAL_FOR_BUFFER_RECYCLING` (default: true), which may be disabled to prevent use of ThreadLocal-based buffer recyling. (suggested by soldierkam@github) #195: Add `JsonGenerator.getOutputBuffered()` to find out amount of content buffered, not yet flushed. (requested by Ruediger M) #196: Add support for `FormatFeature` extension, for format-specifc Enum-backed parser/generator options - Minor improvement to construction of "default PrettyPrinter": now overridable by data format modules - Implement a new yet more optimized symbol table for byte-backed parsers - Add `JsonParser.Feature.IGNORE_UNDEFINED`, useful for data formats like protobuf - Optimize writing of String names (remove intermediate copy; with JDK7 no speed benefit) 详细信息请查看发行页面： https://github.com/FasterXML/jackson-core/releases 此版本现已提供下载： Source code (zip) Source code (tar.gz) Jackson 是一个 Java 用来处理 JSON 格式数据的类库，性能非常好。 Jackson 2.6.0 发布，高性能的 JSON 处理下载地址
