JsonPath —— JSON 解析神器

//输出book[0]的author值
String author = JsonPath.read(json, "$.store.book[0].author");
System.out.println("author\t"+author);
//输出全部author的值，使用Iterator迭代
List authors = JsonPath.read(json, "$.store.book[*].author");
System.out.println("authors\t"+authors);
//输出book[*]中category == 'reference'的book
List
System.out.println("books\t"+books);
//输出book[*]中category == 'reference'的book或者
List
System.out.println("books2\t"+books2);
//输出book[*]中category == 'reference'的book的author
List
System.out.println("books1\t"+books1);
//输出book[*]中price>10的book
List
System.out.println("b1"+b1);
//输出book[*]中含有isbn元素的book
List
System.out.println("b2"+b2);
//输出该json中所有price的值
List prices = JsonPath.read(json, "$..price");
System.out.println("prices"+prices);
//输出该json中所有title的值
List title = JsonPath.read(json, "$..title");
System.out.println("title"+title);
//输出该json中book 0,1的值
List book01 = JsonPath.read(json, "$..book[0,1]");
System.out.println("book01"+book01);
/* //输出该json中book 0,1的值
List book012 = JsonPath.read(json, "$..book[-2:]");
System.out.println("book012"+book012);*/
//可以提前编辑一个路径，并多次使用它
JsonPath path = JsonPath.compile("$.store.book[*]");
List
System.out.println("path\t"+path+"\n"+b3);
