{
    "glossary": {
        "title": "example glossary", 
        "GlossDiv": {
            "title": "S", 
            "GlossList": {
                "GlossEntry": {
                    "ID": "SGML", 
                    "SortAs": "SGML", 
                    "GlossTerm": "Standard Generalized Markup Language", 
                    "Acronym": "SGML", 
                    "Abbrev": "ISO 8879:1986", 
                    "GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook."
                    }, 
                    "GlossSee": "markup"
                }
            }
        }
    }
}

需要获取到这个json的所有字符串并打印在控制台,所有的分献上

问题补充:

新手建议自己手动解析,熟练之后再去用一些解析框架.

没看懂

@你的月亮我的心cy: 这个json对象里面有对象嵌套多个,它的getset方法我都做完了.现在要把它打印到控制台上,用jackson1.7.6

@你的月亮我的心cy: 昨天代码发乱了,我重新发了,帮我看看
