如果你想创建一个数字旋转并且你想在IE中使用它，那么我建议你改用@Region("deltaTesting") public class DeltaTesting implements Delta,Serializable { private static final long serialVersionUID = 1L; public DeltaTesting(){ } public DeltaTesting(String id, String firstName, String lastName){ this.id = id; this.firstName = firstName; this.lastName = lastName; } @Id private String id; private String firstName; private String lastName; private transient boolean stringId = false; private transient boolean stringFirstName = false; private transient boolean stringLastName = false; public String getId() { return id; } public void setId(String id) { this.stringId = true; this.id = id; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.stringFirstName = true; this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.stringLastName = true; this.lastName = lastName; } @Override public void fromDelta(DataInput in) throws IOException, InvalidDeltaException { // TODO Auto-generated method stub System.out.println("Applying delta to " + this.toString()); // For each field, read whether there is a change if (in.readBoolean()) { // Read the change and apply it to the object this.id = in.readLine(); System.out.println(" Applied delta to field 'id' = " + this.id); } if (in.readBoolean()) { // Read the change and apply it to the object this.firstName = in.readLine(); System.out.println(" Applied delta to field 'firstname' = " + this.firstName); } if (in.readBoolean()) { // Read the change and apply it to the object this.lastName = in.readLine(); System.out.println(" Applied delta to field 'lastname' = " + this.lastName); } } @Override public boolean hasDelta() { // TODO Auto-generated method stub return this.stringId || this.stringFirstName || this.stringLastName; } @Override public void toDelta(DataOutput out) throws IOException { out.writeBoolean(stringId); // TODO Auto-generated method stub if (stringId) { out.writeBytes(this.id); this.stringId = false; System.out.println(" Extracted delta from field 'id' = " + this.id); } out.writeBoolean(stringFirstName); if (stringFirstName) { out.writeBytes(this.firstName); this.stringFirstName = false; System.out.println(" Extracted delta from field 'firstName' = " + this.firstName); } out.writeBoolean(stringLastName); if (stringLastName) { out.writeBytes(this.lastName); this.stringLastName = false; System.out.println(" Extracted delta from field 'lastName' = " + this.lastName); } } } **cache.xml** <pdx> <pdx-serializer> <class-name>com.gemstone.gemfire.pdx.ReflectionBasedAutoSerializer</class- name> <parameter name="classes"> <string>com\.xxx\..+</string> </parameter> </pdx-serializer> </pdx> ，因为IE不支持JavaScript，所以你不能使用spin。
