标签：var6 Freemarker 使用 fileOutputStream Throwable import null 方法 templatePath
1.添加依赖
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
</dependency>
2. 范例代码
import com.baomidou.mybatisplus.generator.config.ConstVal;
import freemarker.template.Configuration;
import freemarker.template.Template;
import lombok.extern.slf4j.Slf4j;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.util.HashMap;
import java.util.Map;
@Slf4j
public class FreemarkerTemplate {
private Configuration configuration;
// 推荐使用这种写法，因为Configuration类的构造方法已废弃
public void writer(Map<String, Object> objectMap, String templatePath, String outputFile) throws Exception {
Template template = this.configuration.getTemplate(templatePath);
FileOutputStream fileOutputStream = new FileOutputStream(outputFile);
Throwable var6 = null;
try {
template.process(objectMap, new OutputStreamWriter(fileOutputStream, ConstVal.UTF8));
} catch (Throwable var15) {
var6 = var15;
throw var15;
} finally {
if (fileOutputStream != null) {
if (var6 != null) {
try {
fileOutputStream.close();
} catch (Throwable var14) {
var6.addSuppressed(var14);
}
} else {
fileOutputStream.close();
}
}
}
log.info("模板:" + templatePath + "; 文件:" + outputFile);
}
// 测试方法
public static void writerTest(Map<String, Object> objectMap, String templatePath, String templateFile, String outputFile) throws Exception {
Configuration conf = new Configuration();
//加载模板文件(模板的路径)
conf.setDirectoryForTemplateLoading(new File(templatePath));
// 加载模板
Template template = conf.getTemplate(templateFile);
FileOutputStream fileOutputStream = new FileOutputStream(outputFile);
Throwable var6 = null;
try {
template.process(objectMap, new OutputStreamWriter(fileOutputStream, "UTF-8"));
} catch (Throwable var15) {
var6 = var15;
throw var15;
} finally {
if (fileOutputStream != null) {
if (var6 != null) {
try {
fileOutputStream.close();
} catch (Throwable var14) {
var6.addSuppressed(var14);
}
} else {
fileOutputStream.close();
}
}
}
log.info("模板:" + templatePath + "; 文件:" + outputFile);
}
public static void main(String[] args) throws Exception {
Map<String, Object> map = new HashMap<>();
map.put("name", "zwc");
map.put("age", "18");
map.put("sex", "man");
String fileName = "test";
String templatePath = System.getProperty("user.dir")+"\\src\\main\\resources\\templates\\";
String templateFileName = fileName + ".ftl";
String outputFile = templatePath + "\\create\\"+ fileName +".html";
writerTest(map, templatePath, templateFileName, outputFile);
}
}
3. 扩展其余两种模板引擎（velocity（默认）、Beetl）
3.1 velocity
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import com.baomidou.mybatisplus.generator.config.ConstVal;
import lombok.extern.slf4j.Slf4j;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;
import java.io.BufferedWriter;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.util.Map;
@Slf4j
public class VelocityTemplate {
private VelocityEngine velocityEngine;
public void writer(Map<String, Object> objectMap, String templatePath, String outputFile) throws Exception {
if (!StringUtils.isEmpty(templatePath)) {
Template template = this.velocityEngine.getTemplate(templatePath, ConstVal.UTF8);
FileOutputStream fos = new FileOutputStream(outputFile);
Throwable var6 = null;
try {
OutputStreamWriter ow = new OutputStreamWriter(fos, ConstVal.UTF8);
Throwable var8 = null;
try {
BufferedWriter writer = new BufferedWriter(ow);
Throwable var10 = null;
try {
template.merge(new VelocityContext(objectMap), writer);
} catch (Throwable var54) {
var10 = var54;
throw var54;
} finally {
if (writer != null) {
if (var10 != null) {
try {
writer.close();
} catch (Throwable var53) {
var10.addSuppressed(var53);
}
} else {
writer.close();
}
}
}
} catch (Throwable var56) {
var8 = var56;
throw var56;
} finally {
if (ow != null) {
if (var8 != null) {
try {
ow.close();
} catch (Throwable var52) {
var8.addSuppressed(var52);
}
} else {
ow.close();
}
}
}
} catch (Throwable var58) {
var6 = var58;
throw var58;
} finally {
if (fos != null) {
if (var6 != null) {
try {
fos.close();
} catch (Throwable var51) {
var6.addSuppressed(var51);
}
} else {
fos.close();
}
}
}
log.info("模板:" + templatePath + "; 文件:" + outputFile);
}
}
}
3.2 Beetl
import lombok.extern.slf4j.Slf4j;
import org.beetl.core.GroupTemplate;
import org.beetl.core.Template;
import java.io.FileOutputStream;
import java.util.Map;
@Slf4j
public class BeetlTemplate {
private GroupTemplate groupTemplate;
public void writer(Map<String, Object> objectMap, String templatePath, String outputFile) throws Exception {
Template template = this.groupTemplate.getTemplate(templatePath);
FileOutputStream fileOutputStream = new FileOutputStream(outputFile);
Throwable var6 = null;
try {
template.binding(objectMap);
template.renderTo(fileOutputStream);
} catch (Throwable var15) {
var6 = var15;
throw var15;
} finally {
if (fileOutputStream != null) {
if (var6 != null) {
try {
fileOutputStream.close();
} catch (Throwable var14) {
var6.addSuppressed(var14);
}
} else {
fileOutputStream.close();
}
}
}
log.info("模板:" + templatePath + "; 文件:" + outputFile);
}
}
