将包含字符串
"pictureList":"["http://static.oschina.net/uploads/user/1218/2437072_100.jpg?t=1461076033000","http://common.cnblogs.com/images/icon_weibo_24.png"]"
的json使用JSON.parseArray(json, User.class) 到包含代码
public class User implements Serializable {
private List pictureList;
public List getPictureList() {
return pictureList;
}
public User setPictureList(List pictureList) {
this.pictureList = pictureList;
return this;
}
}
的User.java后，pictureList
应该包含以下两项：
" http://static.oschina.net/uploads/user/1218/2437072_100.jpg?t=1461076033000 "
" http://common.cnblogs.com/images/icon_weibo_24.png "

实际上却只含一项：
"["http://static.oschina.net/uploads/user/1218/2437072_100.jpg?t=1461076033000","http://common.cnblogs.com/images/icon_weibo_24.png"]"

建议解决方法：
当要parse的对象为Collection时，先去掉对应字符串前后的双引号"。

public void test_for_issue() throws Exception {
    String json = "{\"pictureList\":[\"http://static.oschina.net/uploads/user/1218/2437072_100.jpg?t=1461076033000\",\"http://common.cnblogs.com/images/icon_weibo_24.png\"]}";

    User user = JSON.parseObject(json, User.class);
    assertNotNull(user.pictureList);
    assertEquals(2, user.pictureList.size());
    assertEquals("http://static.oschina.net/uploads/user/1218/2437072_100.jpg?t=1461076033000", user.pictureList.get(0));
    assertEquals("http://common.cnblogs.com/images/icon_weibo_24.png", user.pictureList.get(1));
}

public static class User implements Serializable {
    private List<String> pictureList;
    public List<String> getPictureList() {
        return pictureList;
    }
    public User setPictureList(List<String> pictureList) {
        this.pictureList = pictureList;
        return this;
    }
}

我测试到是好的，但可能和你要求不符合

问题就在pictureList这个JSONArray外面加了双引号，"["http://static.oschina...]"，MySQL这边不管用VarChar还是JSON存储，取出来都会自动加上双引号，请问有没有办法去除（不影响正常的字符串）？如果能在MySQL这边解决更好。
