It can also be used to convert a JSON string to an equivalent Java object. Fastjson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.\n\n[FASTJSON 2.0.x](https://github.com/alibaba/fastjson2/releases) has been released, faster and more secure, we recommend you [upgrade](https://github.com/alibaba/fastjson2/wiki/fastjson_1_upgrade_cn) to the latest version.\n\n### Fastjson Goals\n * Provide the best performance on the server-side and android client\n * Provide simple toJSONString() and parseObject() methods to convert Java objects to JSON and vice-versa\n * Allow pre-existing unmodifiable objects to be converted to and from JSON\n * Extensive support of Java Generics\n * Allow custom representations for objects\n * Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)\n\n![fastjson](logo.jpg \"fastjson\")\n\n## Documentation\n\n- [Documentation Home](https://github.com/alibaba/fastjson/wiki)\n- [Contributing Code](https://github.com/nschaffner/fastjson/blob/master/CONTRIBUTING.md)\n- [Frequently Asked Questions](https://github.com/alibaba/fastjson/wiki/%E5%B8%B8%E8%A7%81%E9%97%AE%E9%A2%98)\n- FASTJSON 1.x User Upgrade Guid [https://github.com/alibaba/fastjson2/wiki/fastjson_1_upgrade_cn](https://github.com/alibaba/fastjson2/wiki/fastjson_1_upgrade_cn\n)\n\n## Benchmark\n\n* Eishay benchmark https://github.com/eishay/jvm-serializers/wiki\n* fastjson2 benchmark [https://github.com/alibaba/fastjson2/wiki/fastjson_benchmark](https://github.com/alibaba/fastjson2/wiki/fastjson_benchmark)\n\n\n## Download\n\n- [maven][1]\n- [the latest JAR][2]\n\n[1]: https://repo1.maven.org/maven2/com/alibaba/fastjson/\n[2]: https://search.maven.org/remote_content?g=com.alibaba\u0026a=fastjson\u0026v=LATEST\n\n## Maven\n\n```xml\n\u003cdependency\u003e\n    \u003cgroupId\u003ecom.alibaba\u003c/groupId\u003e\n    \u003cartifactId\u003efastjson\u003c/artifactId\u003e\n    \u003cversion\u003e2.0.31\u003c/version\u003e\n\u003c/dependency\u003e\n```\n\n## Gradle via JCenter\n\n``` groovy\ncompile 'com.alibaba:fastjson:2.0.28'\n```\n\n\nPlease see this [Wiki Download Page][Wiki] for more repository info.\n\n[Wiki]: https://github.com/alibaba/fastjson/wiki#download\n\n### *License*\n\nFastjson is released under the [Apache 2.0 license](license.txt).\n\n```\nCopyright 1999-2020 Alibaba Group Holding Ltd.\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at the following link.\n\n     http://www.apache.org/licenses/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n```\n","funding_links":[],"categories":["Capabilities","Java","CN","Index","Projects","Web 后端","Libraries","Data Format \u0026 I/O","Projects List","HarmonyOS","Java 程序设计","工具类","dependency list","JSON Processing","项目","Infrastructure","III.
