Java系列： 我的第一个spring aop练习

看《Spring in action》有一段时间了，陆续也都看懂了，但是看懂和自己动手写确实是两回事，今天花了几个小时陆续开始安装spring，开始使用DI，然后使用AOP，在写AOP例子代码的过程中遇到一个编译错误，调试了很久，最终找到愿意了，少加了一个jar包，在pom文件中添加之后就ok了。

package com.DbInterface.config;

public interface SetupTable {
public int readSetupNodeByNodeTypeId(int nodeType, int nodeId, boolean includeChild);
public int readAllNodes();
public int writeNode(int nodeType, int nodeId, String nodeName);
public int deleteNode(int nodeType, int nodeId);
}

package com.DbInterface;

import com.DbInterface.config.*;

public class DbInterface {
public SetupTable getSetupTable() {
return setupTable;
}
public void setSetupTable(SetupTable setupTable) {
this.setupTable = setupTable;
}
public RealtimeTable getRealtimeTable() {
return realtimeTable;
}
public void setRealtimeTable(RealtimeTable realtimeTable) {
this.realtimeTable = realtimeTable;
}
public CommandTable getCommandTable() {
return commandTable;
}
public void setCommandTable(CommandTable commandTable) {
this.commandTable = commandTable;
}

private SetupTable setupTable;
private RealtimeTable realtimeTable;
private CommandTable commandTable;
}

package com.DbInterfaceForPG;

import com.DbInterface.config.SetupTable;

public class SetupTableForPG implements SetupTable {

public int readSetupNodeByNodeTypeId(int nodeType, int nodeId, boolean includeChild) {
System.out.println(String.format("readSetupNodeByNodeTypeId, nodeType=%d, nodeId=%d, includeChild=%b", nodeType, nodeId, includeChild));
return 0;
}

public int readAllNodes(){
System.out.println("readAllNodes");
return 0;
}
public int writeNode(int nodeType, int nodeId, String nodeName) {
System.out.println(String.format("writeNode, nodeType=%d, nodeId=%d, nodeName=%s", nodeType, nodeId, nodeName));
return 0;
}

public int deleteNode(int nodeType, int nodeId) {
System.out.println(String.format("deleteNode, nodeType=%d, nodeId=%d", nodeType, nodeId));
return 0;
}

}
