【问题描述】：
我通过单击此类中的 jButton 来运行 main 方法。首先尝试使用
public static void main(String[]args)
所有java swing组件开始显示non static variable cannot be referenced from static content错误。所以我改变了
public static void main(String[]args)
到
public void main(String[]args)
swing 组件未显示错误，但 jTextArea 中未显示预期结果。如果我在 System.out.println 中打印预期的输出，它会正确显示。我在这里做错了什么？这就是我通过单击 jButton 触发 main() 运行的方式
jButton4.setText("Analyze");
jButton4.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
try{
TestTextRazor test = new TestTextRazor();
test.main(new String[0]);
}
catch (Exception e) {
e.printStackTrace();
}
}
});
这是我的 main()
public void main(String[] args) throws NetworkException, AnalysisException {
File textSRC = new File("MyText.txt");
String myTextCount = null;
BufferedReader myTextBr = null;
String check = "";
try {
String myTextCurrentLine;
myTextBr = new BufferedReader(new FileReader(textSRC));
while ((myTextCurrentLine = myTextBr.readLine()) != null) {
myTextCount = myTextCount + " " + myTextCurrentLine;
}
// Sample request, showcasing a couple of TextRazor features
String API_KEY = "7d5066bec76cb47f4eb4e557c60e9b979f9a748aacbdc5a44ef9375a";
TextRazor client = new TextRazor(API_KEY);
client.addExtractor("words");
client.addExtractor("entities");
client.addExtractor("entailments");
client.addExtractor("senses");
client.addExtractor("entity_companies");
String rules = "entity_companies(CompanyEntity) :- entity_type(CompanyEntity, 'Company').";
client.setRules(rules);
AnalyzedText response = client.analyze(myTextCount);
File file = new File("Hello1.txt");
// creates the file
file.createNewFile();
// creates a FileWriter Object
FileWriter writer = new FileWriter(file);
// Writes the content to the file
for (Sentence sentence : response.getResponse().getSentences()) {
for (Word word : sentence.getWords()) {
System.out.println("----------------");
System.out.println("Word: " + word.getLemma());
for (Entity entity : word.getEntities()) {
///System.out.println("Matched Entity: " + entity.getEntityId());
}
for (Sense sense: word.getSenses()) {
//System.out.println("Word sense: " + sense.getSynset() + " has score: " + sense.getScore());
}
}
}
// Use a custom rule to match 'Company' type entities
for (Custom custom : response.getResponse().getCustomAnnotations()) {
for (Custom.BoundVariable variable : custom.getContents()) {
if (null != variable.getEntityValue()) {
for (Entity entity : variable.getEntityValue()) {
String CompanyFound = ("Variable: " + variable.getKey() +"\n"+ "Value:" + entity.getEntityId());
System.out.println(CompanyFound);
jTextArea3.append(CompanyFound);
writer.write(CompanyFound);
writer.flush();
writer.close();
}
}
}
}
String ObjButtons[] = {"Yes","No"};
int PromptResult;
PromptResult = JOptionPane.showOptionDialog(null,"Completed Analysis!\nIs there any error in the Analysis?","Homonym Entity Extraction Application",JOptionPane.DEFAULT_OPTION,JOptionPane.WARNING_MESSAGE,null,ObjButtons,ObjButtons[1]);
//JOptionPane.getAlignmentX(Component.BOTTOM_ALIGNMENT);
if(PromptResult==JOptionPane.YES_OPTION)
{
System.out.println("YEs!!!!!");
jTextArea2.setEditable(true);
jTextArea3.setEditable(true);
jButton4.setEnabled(false);
jButton5.setEnabled(true);
}
else{
JOptionPane.showMessageDialog(null, "Completed Analysis!","Alert", 1);
System.out.println("No!!!!!!!!!!");
jTextArea2.setEditable(false);
jTextArea3.setEditable(false);
jButton4.setEnabled(false);
}
}catch (IOException ex) {
}
}
请指导我。
【问题讨论】：
-
拜托，请拿一本书读一读。了解“静态”的含义。
-
修复你的第一个错误（来自静态上下文的非静态）
-
对于
Swing程序，我不会在main方法中投入太多，看看Swing tutorials中的一些，您可能会从中学到一些更好的做法。将来也可以帮助您避免这个static问题。
