动态生成java源代码(不带xjc)

Question

有没有人设法从没有XJC的JAXB模式文件生成Java代码？

有点类似

JavaCompiler javaCompiler = ToolProvider.getSystemJavaCompiler()

用于动态编译Java代码.

注意:在JDK 6上运行,意味着com.sun.*不推荐使用工具包(感谢Blaise Doughan的提示)

Answer 1

我必须为我的解决方案包含一些J2EE库才能工作,因为独立的JDK 6无法访问xjc实用程序类:

import com.sun.codemodel.*;
import com.sun.tools.xjc.api.*;
import org.xml.sax.InputSource;

// Configure sources & output
String schemaPath = "path/to/schema.xsd";
String outputDirectory = "schema/output/source/";

// Setup schema compiler
SchemaCompiler sc = XJC.createSchemaCompiler();
sc.forcePackageName("com.xyz.schema.generated");

// Setup SAX InputSource
File schemaFile = new File(schemaPath);
InputSource is = new InputSource(new FileInputStream(schemaFile));
is.setSystemId(schemaFile.getAbsolutePath());

// Parse & build
sc.parseSchema(is);
S2JJAXBModel model = sc.bind();
JCodeModel jCodeModel = model.generateCode(null, null);
jCodeModel.build(new File(outputDirectory));

*.java源将放在outputDirectory中
