IDEA有自带的数据库table 生成对应的POJOs的脚本，但是不是很好用，生成的包名不对，而且没有添加JPA的注解，所以自己就对着原版修改了下，希望对大家有用.
添加了@Entity、@Table、@Data三个类注解，lombok依赖自己添加。添加了@Column 注解包名不再写死，会根据项目生成正确的包名。有了lombok ，去掉了get、set方法。 import com.intellij.database.model.DasTable import com.intellij.database.util.Case import com.intellij.database.util.DasUtil /* * Available context bindings: * SELECTION Iterable<DasObject> * PROJECT project * FILES files helper */ //packageName = "com.sample;" typeMapping = [ (~/(?i)int/) : "Integer", (~/(?i)float|double|decimal|real/): "double", (~/(?i)datetime|timestamp/) : "java.sql.Timestamp", (~/(?i)date/) : "java.sql.Date", (~/(?i)time/) : "java.sql.Time", (~/(?i)/) : "String" ] FILES.chooseDirectoryAndSave("Choose directory", "Choose where to store generated files") { dir -> SELECTION.filter { it instanceof DasTable }.each { generate(it, dir) } } def generate(table, dir) { def className = javaName(table.getName(), true) def fields = calcFields(table) new File(dir, className + ".java").withPrintWriter { out -> generate(dir, out, className, fields, table) } } def generate(dir, out, className, fields, table) { out.println "package " + dir.getAbsolutePath().split("main.java.")[1] .replace("\\", ".").replaceAll("/", ".") + ";" out.println "" out.println "" out.println "" out.println "import lombok.Data;\n" + "\n" + "import javax.persistence.Column;\n" + "import javax.persistence.Entity;\n" + "import javax.persistence.Id;\n" + "import javax.persistence.Table;" out.println "" out.println "" out.println "" out.println "" out.println "@Entity" out.println "@Table(name = \"" + table.getName() + "\")" out.println "@Data" out.println "public class $className {" out.println "" fields.each() { if (it.annos != "") out.println " ${it.annos}" if (it.name == "id") out.println " @Id" else out.println " @Column(name = \"" + it.colname + "\")" out.println " private ${it.type} ${it.name};" } out.println "" // fields.each() { // out.println "" // out.println " public ${it.type} get${it.name.capitalize()}() {" // out.println " return ${it.name};" // out.println " }" // out.println "" // out.println " public void set${it.name.capitalize()}(${it.type} ${it.name}) {" // out.println " this.${it.name} = ${it.name};" // out.println " }" // out.println "" // } out.println "}" } def calcFields(table) { DasUtil.getColumns(table).reduce([]) { fields, col -> def spec = Case.LOWER.apply(col.getDataType().getSpecification()) def typeStr = typeMapping.find { p, t -> p.matcher(spec).find() }.value fields += [[ name : javaName(col.getName(), false), type : typeStr, colname: col.getName(), annos : ""]] } } def javaName(str, capitalize) { def s = com.intellij.psi.codeStyle.NameUtil.splitNameIntoWords(str) .collect { Case.LOWER.apply(it).capitalize() } .join("") .replaceAll(/[^\p{javaJavaIdentifierPart}[_]]/, "_") capitalize || s.length() == 1 ? s : Case.LOWER.apply(s[0]) + s[1..-1] }
