我正在使用Spring集成通过私钥连接到SFTP Server。 私钥作为外部字符串进入应用程序。如何在以下代码中使用密钥：
<bean id="test"
class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
<property name="host" value="${host}" />
<property name="privateKey" value="" />
<property name="port" value="${port}" />
<property name="user" value="${username}" />
<property name="allowUnknownKeys" value="true" />
</bean>

如果您的意思是密钥的编码方式类似于某个字符串，那么您需要考虑将其包装到 public static int bestMoves(char[][] coordinates, int movesPossible, int playerX, int playerY, int mapSize, boolean[][] visited){
char[][] mapCopy = new char[mapSize][mapSize];
boolean[][] visitedCopy = new boolean[mapSize][mapSize];
for (int i = 0; i < mapSize; i++){
for (int j = 0; j < mapSize; j++){
mapCopy[i][j] = coordinates[i][j];
}
}
for (int i = 0; i < mapSize; i++){
for (int j = 0; j < mapSize; j++){
visitedCopy[i][j] = visited[i][j];
}
}
if (movesPossible > 0){
if (playerX - 1 >=0 && !visited[playerY][playerX-1]){
visitedCopy[playerX-1][playerY] = true;
if (coordinates[playerY][playerX-1] == '1'){
return 1 + bestMoves(mapCopy, movesPossible-1, playerX-1, playerY, mapSize-1,visited);
}else{
return bestMoves(mapCopy, movesPossible-1, playerX-1, playerY, mapSize-1,visited);
}
}
if (playerY - 1 >=0 && !visited[playerY-1][playerX]){
visitedCopy[playerY-1][playerX] = true;
if (coordinates[playerY-1][playerX] == '1'){
return 1 + bestMoves(mapCopy, movesPossible-1, playerX, playerY-1, mapSize-1,visited);
}else{
return bestMoves(mapCopy, movesPossible-1, playerX, playerY-1, mapSize-1,visited);
}
}
else if (playerY + 1 >= mapSize && !visited[playerY-1][playerX]){
visitedCopy[playerY][playerX] = true;
if (coordinates[playerY+1][playerX] == '1'){
return 1 + bestMoves(mapCopy, movesPossible-1, playerX, playerY+1, mapSize-1,visited);
}else{
return bestMoves(mapCopy, movesPossible-1, playerX, playerY+1, mapSize-1,visited);
}
}
else if (playerX + 1 >= mapSize && !visited[playerY-1][playerX]){
visitedCopy[playerY][playerX] = true;
if (coordinates[playerY+1][playerX] == '1'){
return 1 + bestMoves(mapCopy, movesPossible-1, playerX+1, playerY, mapSize-1,visited);
}else{
return bestMoves(mapCopy, movesPossible-1, playerX+1, playerY, mapSize-1,visited);
}
}else{
return 0;
}
}else{
return 0;
}
中。
我们假设您将其作为某个文件中的属性，并且使用属性占位符：
