Spring Boot Learning (d) Web Development rendering page--Freemarker__web

The Web Development Rendering page of Spring boot learning (d) was written in the previous chapter--Thymeleaf

Next, let's take a look at Freemarker integration Springboot

See controller:

    @RequestMapping ("/") public
    String index (Modelmap map) {
        map.addattribute ("name", "Xiao Jin gg");
        Return "index";

Write a HELLO.FTL file that has a path under Src/main/resources/templates, where the contents of the HELLO.FTL file are as follows:

<! DOCTYPE html>
 
We can start our program for testing, access to the address:

Http://127.0.0.1:8080/hello, if you see the following message in your browser:

Freemarker template engine welcome Xiao into GG to freemarker!

Well, that means you're OK.

freemarker Configuration:

Some common configurations for Freemarker are provided in the Application.properties properties file of Spring boot, as follows:

Spring.freemarker.allow-request-override=false # Set Whether HttpServletRequest attributes are allowed to override (hide
) controller generated model attributes of the same name. Spring.freemarker.allow-session-override=false # Set Whether HttpSession attributes are allowed to override (hide) contro
Ller generated model attributes of the same name.
Spring.freemarker.cache=false # Enable Template caching.
Spring.freemarker.charset=utf-8 # Template encoding.
Spring.freemarker.check-template-location=true # Check that the templates location exists.
Spring.freemarker.content-type=text/html # Content-type value.
Spring.freemarker.enabled=true # Enable MVC View resolution for this technology. Spring.freemarker.expose-request-attributes=false # Set Whether all request attributes should is added to the model prior
To merging with the template. Spring.freemarker.expose-session-attributes=false # Set Whether all HttpSession attributes should is added to the model PR IOR to merging with the template. Spring.freemarker.expose-spring-macro-helpers=true # Set whether to expose a requestcontext for use by spring ' s macro libr
ary, under the name "Springmacrorequestcontext". Spring.freemarker.prefer-file-system-access=true # prefer file system access for template loading.
The File system access enables hot detection of template changes.
spring.freemarker.prefix= # prefix that gets prepended to view names when building a URL.
The spring.freemarker.request-context-attribute= # Name of the RequestContext attribute for all views.
spring.freemarker.settings.*= # well-known Freemarker keys which'll is passed to Freemarker ' s Configuration.
spring.freemarker.suffix= # suffix that gets appended to view names when building a URL.
spring.freemarker.template-loader-path=classpath:/templates/# comma-separated List of template paths. spring.freemarker.view-names= # White List of view names so can be resolved.
 
Parameter default configuration, can write or write

Spring.freemarker.allow-request-override=false
spring.freemarker.cache=true
Spring.freemarker.check-template-location=true
Spring.freemarker.charset=utf-8
spring.freemarker.content-type=text/html
Spring.freemarker.expose-request-attributes=false
Spring.freemarker.expose-session-attributes=false
Spring.freemarker.expose-spring-macro-helpers=false
#spring. freemarker.prefix=
#spring. freemarker.request-context-attribute=
#spring. freemarker.settings.* =
#spring. FREEMARKER.SUFFIX=.FTL
#spring. freemarker.template-loader-path=classpath:/templates/ comma-separated list
#spring. freemarker.view-names= # Whitelist of view names that can is resolved
 
To modify the Index method:

   @RequestMapping ("/") public
    String index (Modelmap map) {
        map.addattribute ("name", "Xiao Jin gg");
        Map.put ("Gender", 1);//gender: Sex, 1: male; 0: female;
        list<map<string,object>> friends =new <String,Object>> ();
        map<string,object> friend = new hashmap<string,object> ();
        Friend.put ("name", "John");
        Friend.put ("Age");
        Friends.add (friend);
        Friend = new hashmap<string,object> ();
        Friend.put ("name", "Dick");
        Friend.put ("Age");
        Friends.add (friend);
        Map.put ("Friends", friends);
        Return "index";
    
 
Modify Page

<! DOCTYPE html>
 
To restart a running project:

Http://127.0.0.1:8080/hello can see

Freemarker Template engine

Welcome Xiao into GG to freemarker!

My friend:

Name: John, age 20

At this point, Freemarker integration Springboot is complete!
