摘要：最佳解析最佳解析最佳解析是一個(gè)依賴注入框架，由谷歌開發(fā)，最早的版本由公司開發(fā)。在對的介紹中指出，即，這里的即數(shù)據(jù)結(jié)構(gòu)中的有向無環(huán)圖。也就是說，是一個(gè)基于有向無環(huán)圖結(jié)構(gòu)的依賴注入庫，因此的使用過程中不能出現(xiàn)循環(huán)依賴。

在開發(fā)過程中使用過很多優(yōu)秀框架，比如網(wǎng)絡(luò)的okhttp，圖片的Fresco，注入的Gagger2等，都是非常優(yōu)秀的框架。

所以今天在此介紹下至今本人知道的一些比較流行主流且很優(yōu)秀的框架。

根據(jù)上圖我們依次說明：

This is the home page of the Jackson Project, formerly known as the standard JSON library for Java (or JVM platform in general), or, as the "best JSON parser for Java." Or simply as "JSON for Java." 

    More than that, Jackson is a suite of data-processing tools for Java (and the JVM platform), including the flagship streaming JSON parser / generator library, matching data-binding library (POJOs to and from JSON) and additional data format modules to process data encoded in Avro, BSON, CBOR, CSV, Smile, Protobuf, XML or YAML; 

    and even the large set of data format modules to support data types of widely used data types such as Joda, Guava and many, many more.

    While the actual core components live under their own projects -- including the three core packages (streaming, databind, annotations; 

    data format libraries; data type libraries; JAX-RS provider; 

    and a miscellaneous set of other extension modules -- this project act as the central hub for linking all the pieces together.

Dagger2 是一個(gè)Android依賴注入框架，由谷歌開發(fā)，最早的版本Dagger1由Square公司開發(fā)。

    依賴注入框架主要用于模塊間解耦，提高代碼的健壯性和可維護(hù)性。

    Dagger這個(gè)庫的取名不僅僅來自它的本意“匕首”，同時(shí)也暗示了它的原理。

    Jake Wharton 在對 Dagger 的介紹中指出，Dagger 即DAG-er，這里的 DAG 即數(shù)據(jù)結(jié)構(gòu)中的 DAG——有向無環(huán)圖(Directed Acyclic Graph)。

    也就是說，Dagger是一個(gè)基于有向無環(huán)圖結(jié)構(gòu)的依賴注入庫，因此Dagger的使用過程中不能出現(xiàn)循環(huán)依賴。
