如何配置

1. 首先明确下数据库有哪些表
   
2. 接着来看具体的配置
   

启动程序

	public void generator() throws Exception {
    
    

		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		//指定 逆向工程配置文件
		File configFile = new File("generatorConfig.xml");
		ConfigurationParser cp = new ConfigurationParser(warnings);
		Configuration config = cp.parseConfiguration(configFile);
		DefaultShellCallback callback = new DefaultShellCallback(overwrite);
		MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
				callback, warnings);
		myBatisGenerator.generate(null);

	} 
	
	public static void main(String[] args) throws Exception {
    
    
		try {
    
    
			GeneratorDisplay generatorSqlmap = new GeneratorDisplay();
			generatorSqlmap.generator();
		} catch (Exception e) {
    
    
			e.printStackTrace();
		}
		
	}

讲道理，这方法我也不懂。可以理解为工具类吧，反正直接复制过去就能用。直接运行就对了！奥利给！

配置文件记得放在根目录下，就是和pom.xml平级

结果

自动生成了mapper，pojo和xml文件啦！
