小编kid*_*uxa的帖子

我无法在Eclipse中的Bitbucket中克隆或推送到git存储库:

这很奇怪,因为前一天我没有任何问题.我已经下载了3次没有运气的sts.此错误一直显示.我也安装了SourceTree,它说'这不是一个有效的源路径/ URL':

如果我使用git命令导入项目,它可以工作,但我不想使用EGit执行此任务,因为我是git的新手.

我不知道这是否与它有关,但在同一目录中我有android-adt-bundle.这个工作得很好,但项目在于GitHub,而不是Bitbucket.此外,我正在与另一个人合作,他能够从Bitbucket存储库获取数据并将数据推送到Bitbucket存储库.我看了很多帖子,但没有一个人帮助过我.

我正在使用Windows 7顺便说一句.

一位朋友给我发了一个Maven项目,我试图在我的计算机上本地运行.我在Eclipse中所做的一切,我选择了:

文件 - >导入 - >现有的Maven项目

在那之后,该项目向我展示了我的4个错误pom.xml(Missing artifact ..):

我尝试删除.m2文件夹的内容,然后在Eclipse中我点击了我的项目并选择"Run as" - >"Maven clean"然后"Run as" - >"Maven install".但我仍然有同样的错误.我是Spring的新手,所以我不知道还能做什么.

编辑:

当我尝试这样做:运行as/maven install时,这就是我的控制台所说的:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

我看过这篇文章,但这里发布的解决方案对我不起作用:在backstack中获取最新的片段

当我替换另一个片段时,我使用:

FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction ft = manager.beginTransaction();

    ft.replace(android.R.id.tabcontent, fragment, tag);
    ft.addToBackStack(null);

    ft.commit();

所以,请注意我正在使用标签来检测任何片段.

我的问题尤其如下:

假设我有fragment_A,fragment_B和fragment_C.我可以从fragment_A或fragment_B获取fragment_C,并且根据调用的父级,我必须做一些特别的事情.所以,我再次需要恢复后堆栈中的最后一个FRAGMENT.

当我尝试做的时候:

FragmentManager fm = getSupportFragmentManager();

        for(int entry = 0; entry < fm.getBackStackEntryCount(); entry++){
            String ide = fm.getBackStackEntryAt(entry).getName();
           Log.i("TAG", "Found fragment: " + ide);
        }

我得到零.如果我使用getId()代替,我得到数字,所以我尝试做:

int id = fm.getBackStackEntryAt(entry).getId();
Fragment fragment = fm.findFragmentById(id);
Log.i("TAG", "Found fragment: " + fragment.getTag());

但我得到了空的..我不知道还能做什么,所以任何帮助将不胜感激.

编辑:我在onBackPressed(){...}中调用此方法

我最近遇到了这个问题,我想与您分享我的解决方案.

问题:

• 你有一个ListView,每行有一个编辑文本,如下所示:

MainList.xml

<ListView
    android:id="@+id/listViewServ"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"/>

RowList.xml

<TextView 
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="100dp"
        android:layout_height="wrap_content"  
        android:inputType="number"/>

• 您正在使用TABS:tabHost或TabActivity.(这一点非常重要).
• 当您单击任何列表项EditText时,焦点会立即移出,您无法键入任何内容.然而键盘仍然打开.但是你输入的东西并没有出现,因为焦点丢失了.

现在,我将给你解决方案,发布我自己的问题.

我试图在带有sherlock的操作栏中使用抽屉切换.这是我的主要活动:

        setContentView(R.layout.activity_main);

        pullToRefreshAttacher = PullToRefreshAttacher.get(this);

        drawer_list = (ListView) findViewById(R.id.left_drawer);
        drawer_layout = (DrawerLayout) findViewById(R.id.drawer_layout);

        ArrayAdapter<String> drawer_adapter = new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, getResources().getStringArray(
                        R.array.array_drawer_options));

        drawer_list.setAdapter(drawer_adapter); …

我想知道如何使用注释@ManyToMany创建表role_permission,同时考虑表role_permission中的属性created_at.

我知道我可以这样做:

public class Role implements Serializable{

    @Id
    @Column(name = "_id")
    private String id;

    @Column(name = "name")
    @NotNull
    private String name;

    @Column(name = "description")
    private String description;

    @ManyToMany(cascade = {CascadeType.ALL})
    @JoinTable(name="role_permission", schema=joinColumns={@JoinColumn(name="idRole")}, inverseJoinColumns={@JoinColumn(name="idPermission")})
    private Set<Permission> permissions=new HashSet();

和

public class Permission implements Serializable{

    @Id
    @Column(name = "_id")
    private String id;

    @Column(name = "name")
    @NotNull
    private String name;

    @Column(name = "description")
    private String description;

    @ManyToMany(cascade = {CascadeType.ALL})
    @JoinTable(name="role_permission", schema=joinColumns={@JoinColumn(name="idPermission")}, inverseJoinColumns={@JoinColumn(name="idRole")})
    private Set<Permission> roles=new HashSet();

有了这个,我可以避免为role_permission创建一个新类,但我不知道如何将created_at放在这个注释中.这可能吗？
