jooq使用自定义策略生成代码（How to use a custom strategy with the jOOQ code-generator and Maven?）
工程结构：
- generator子模块，用于自定义策略
- jooq模块为父模块，用于实现业务
自定义代码生成策略：MyStratege
package com.code.generator.stratege;
import org.jooq.tools.StringUtils;
import org.jooq.util.CatalogDefinition;
import org.jooq.util.DefaultGeneratorStrategy;
import org.jooq.util.Definition;
import org.jooq.util.SchemaDefinition;
public class MyStratege extends DefaultGeneratorStrategy {
public String getJavaClassName(Definition definition, Mode mode) {
String name = getFixedJavaClassName(definition);
return name != null ? name : this.getJavaClassName0(definition, mode);
}
private String getJavaClassName0(Definition definition, Mode mode) {
StringBuilder result = new StringBuilder();
result.append(StringUtils.toCamelCase(definition.getOutputName().replace(' ', '_').replace('-', '_').replace('.', '_')));
if (mode == Mode.RECORD) {
result.append("Record");
} else if (mode == Mode.DAO) {
result.append("Dao");
} else if (mode == Mode.POJO) {
result.append("Bo");
} else if (mode == Mode.INTERFACE) {
result.insert(0, "I");
}
return result.toString();
}
final String getFixedJavaClassName(Definition definition) {
if (definition instanceof CatalogDefinition && ((CatalogDefinition) definition).isDefaultCatalog()) {
return "DefaultCatalog";
} else {
return definition instanceof SchemaDefinition && ((SchemaDefinition) definition).isDefaultSchema() ? "DefaultSchema" : null;
}
}
}
