springboot中freemarker的默认配置

package org.springframework.boot.autoconfigure.freemarker;

import java.util.HashMap;
import java.util.Map;
import org.springframework.boot.autoconfigure.template.AbstractTemplateViewResolverProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(
    prefix = "spring.freemarker"//配置文件默认前缀
)
public class FreeMarkerProperties extends AbstractTemplateViewResolverProperties {
    public static final String DEFAULT_TEMPLATE_LOADER_PATH = "classpath:/templates/";//默认静态资源位置
    public static final String DEFAULT_PREFIX = "";//默认前缀
    public static final String DEFAULT_SUFFIX = ".ftl";//默认后缀
    private Map<String, String> settings = new HashMap();
    private String[] templateLoaderPath = new String[]{"classpath:/templates/"};
    private boolean preferFileSystemAccess = true;

    public FreeMarkerProperties() {
        super("", ".ftl");
    }

    //省略...
	//其他见父类
}

示例

依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

简单配置

spring:
  freemarker:
    cache: false #生成环境可设置为true
    template-loader-path: classpath:/static
    suffix: .ftl

页面模板

在resource目录下新建目录 static，然后新建个文件 index.ftl

web处理器

添加一个springmvc控制器

@Controller
public class IndexController {
    @RequestMapping({"","index"})
    public String index(Model model){
        model.addAttribute("name", "哈哈哈");
        return "index";
    }
}
