java Alphacomposite (이미지 겹침 처리)

https://docs.oracle.com/javase/tutorial/2d/advanced/compositing.html
http://www.java2s.com/Tutorial/Java/0261__2D-Graphics/AlphaCompositeDSTIN.htm

Compositing Graphics

The AlphaComposite class encapsulates various compositing styles, which determine how overlapping objects are rendered. An AlphaComposite can also have an alpha value that specifies the degree of transparency: alpha = 1.0 is totally opaque, alpha = 0.0 totally transparent (clear). AlphaComposite supports most of the standard Porter-Duff compositing rules shown in the following table.

Compositing Rule	Description
Source-over (SRC_OVER)	If pixels in the object being rendered (the source) have the same location as previously rendered pixels (the destination), the source pixels are rendered over the destination pixels.
Source-in (SRC_IN)	If pixels in the source and the destination overlap, only the source pixels in the overlapping area are rendered.
Source-out (SRC_OUT)	If pixels in the source and the destination overlap, only the source pixels outside of the overlapping area are rendered. The pixels in the overlapping area are cleared.
Destination-over (DST_OVER)	If pixels in the source and the destination overlap, only the source pixels outside of the overlapping area are rendered. The pixels in the overlapping area are not changed.
Destination-in (DST_IN)	If pixels in the source and the destination overlap, the alpha from the source is applied to the destination pixels in the overlapping area. If the alpha = 1.0, the pixels in the overlapping area are unchanged; if the alpha is 0.0, pixels in the overlapping area are cleared.
Destination-out (DST_OUT)	If pixels in the source and the destination overlap, the alpha from the source is applied to the destination pixels in the overlapping area. If the alpha = 1.0, the pixels in the overlapping area are cleared; if the alpha is 0.0, the pixels in the overlapping area are unchanged.
Clear (CLEAR)	If the pixels in the source and the destination overlap, the pixels in the overlapping area are cleared.

To change the compositing style used by the Graphics2D class, create an AlphaComposite object and pass it into the setComposite method.

Example: Composite

This program illustrates the effects of various compositing style and alpha combinations.

Note:  If you don't see the applet running, you need to install at least the Java SE Development Kit (JDK) 7 release.

---

Composite.java. contains the full code for this applet.
A new AlphaComposite object ac is constructed by calling AlphaComposite.getInstance and specifying the desired compositing rule.

AlphaComposite ac =
  AlphaComposite.getInstance(AlphaComposite.SRC);

When a different compositing rule or alpha value is selected, AlphaComposite.getInstance is called again, and the new AlphaComposite is assigned to ac. The selected alpha is applied in addition to the per-pixel alpha value and is passed as a second parameter to AlphaComposite.getInstance.

ac = AlphaComposite.getInstance(getRule(rule), alpha);

The composite attribute is modified by passing the AlphaComposite object to Graphics 2D setComposite. The objects are rendered into a BufferedImage and are later copied to the screen, so the composite attribute is set on the Graphics2D context for the BufferedImage:

BufferedImage buffImg = new BufferedImage(w, h,
                        BufferedImage.TYPE_INT_ARGB);
Graphics2D gbi = buffImg.createGraphics();
...
gbi.setComposite(ac);

jpa @OneToMany(mappedBy="?", fetch=FetchType.LAZY) 일때 @responsebody 오류날 경우

http://stackoverflow.com/questions/3325387/infinite-recursion-with-jackson-json-and-hibernate-jpa-issue

Since Jackson 1.6 you can use two annotations to solve the infinite recursion problem without ignoring the getters/setters during serialization: @JsonManagedReference and @JsonBackReference.

Explanation

For Jackson to work well, one of the two sides of the relationship should not be serialized, in order to avoid the infite loop that causes your stackoverflow error.

So, Jackson takes the forward part of the reference (your Set<BodyStat> bodyStats in Trainee class), and converts it in a json-like storage format; this is the so-called marshalling process. Then, Jackson looks for the back part of the reference (i.e. Trainee trainee in BodyStat class) and leaves it as it is, not serializing it. This part of the relationship will be re-constructed during the deserialization (unmarshalling) of the forward reference.

You can change your code like this (I skip the useless parts):

Business Object 1:

@Entity
@Table(name = "ta_trainee", uniqueConstraints = {@UniqueConstraint(columnNames = {"id"})})
public class Trainee extends BusinessObject {

    @OneToMany(mappedBy = "trainee", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @Column(nullable = true)
    @JsonManagedReference
    private Set<BodyStat> bodyStats;

Business Object 2:

@Entity
@Table(name = "ta_bodystat", uniqueConstraints = {@UniqueConstraint(columnNames = {"id"})})
public class BodyStat extends BusinessObject {

    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinColumn(name="trainee_fk")
    @JsonBackReference
    private Trainee trainee;

Now it all should work properly.

If you want more informations, I wrote an article about Json and Jackson Stackoverflow issues on Keenformatics, my blog.

EDIT:

Another useful annotation you could check is @JsonIdentityInfo: using it, everytime Jackson serializes your object, it will add an ID (or another attribute of your choose) to it, so that it won't entirely "scan" it again everytime. This can be useful when you've got a chain loop between more interrelated objects (for example: Order -> OrderLine -> User -> Order and over again).

In this case you've got to be careful, since you could need to read your object's attributes more than once (for example in a products list with more products that share the same seller), and this annotation prevents you to do so. I suggest to always take a look at firebug logs to check the Json response and see what's going on in your code.
