方法摘要

static Object	bytes2Object(byte[] jsonBytes, Class<?> c)
static Object	convertValue(Object val, org.codehaus.jackson.type.JavaType type)
static org.codehaus.jackson.map.ObjectMapper	getObjectMapper()
static <T> T	json2GenericObject(String jsonString, org.codehaus.jackson.type.TypeReference<T> tr) JSON串转换为Java泛型对象，可以是各种类型，此方法最为强大。
static Object	json2Object(String jsonString, Class<?> c) Json字符串转Java对象
static Object	json2Object(String jsonString, org.codehaus.jackson.type.JavaType type)
static String	toJson(Object object) Java对象转Json字符串
static String	toJson(Object object, boolean ignoreEmpty)
static byte[]	toJsonBytes(Object object)
static byte[]	toJsonBytes(Object object, boolean ignoreEmpty)

方法详细信息

getObjectMapper

public static org.codehaus.jackson.map.ObjectMapper getObjectMapper()

json2GenericObject

public static <T> T json2GenericObject(String jsonString,
                                       org.codehaus.jackson.type.TypeReference<T> tr)

JSON串转换为Java泛型对象，可以是各种类型，此方法最为强大。用法看测试用例。

类型参数：

T -

参数：

jsonString - JSON字符串

tr - TypeReference,例如: new TypeReference< List >(){}

返回：

List对象列表
