[Solved] java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed

Project scenario:

Spring boot project, user-defined filter, intercept requests and process business.

Problem Description:

When you start the project access interface, you call resp.sendRedirect () in the custom filter.

Cause analysis:

After the response has been submitted, the sendredirect() method cannot be called.

In fact, chain. Dofilter (req, resp) is executed; Cannot use sendredirect() of resp object after

So looking at the code, we find that:

...

  HttpServletRequest httpRequest = (HttpServletRequest) request;
  HttpServletResponse httpResponse = (HttpServletResponse) response;
  ....
  boolean flag = getStatus();
  if (flag) {
      ....
      chain.doFilter(request, response);
  }
  httpResponse.sendRedirect(“xxxx”);
...

if the judged flag is true, chain.dofilter (request, response) will be executed, and httpresponse.sendredirect (“XXXX”) </ font> will be executed after execution

Solution:

After chain. Dofilter (request, response), add return to end the current method.

...

  HttpServletRequest httpRequest = (HttpServletRequest) request;
  HttpServletResponse httpResponse = (HttpServletResponse) response;
  ....
  boolean flag = getStatus();
  if (flag) {
      ....
      chain.doFilter(request, response);
      return;
  }
  httpResponse.sendRedirect(“xxxx”);
...

[Redirect anomaly] Cannot call sendRedirect() after the response has been committed

Exception: threw exception [request processing failed; nested exception is java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed] with root cause
java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed

Reason:
there is no return after response reset. The subsequent program continues to run and submits the request again, so an error is reported,

When forwarding or redirecting according to conditions, the corresponding forwarding or redirecting statement is followed by return; Or return null;

JAVA Connect MYSQL Error: Path does not chain with any of the trust anchors

Connection address:

jdbcUrl=jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true

There is no problem with MySQL 5.5 on windows, but the connection fails on Mac.

Maybe it’s a certificate problem. Just change usessl = true to usessl = false. If you have time, please study SSL connection.

The error information is as follows:

Path does not chain with any of the trust anchors [Solved]

Path does not chain with any of the trust anchors exception resolution

Problem statement: JDBC. Url = JDBC: mysql://192.168.23.129:3306/ssmbuild?useSSL=true&amp ; useUnicode=true& Characterencoding = utf8
solution: change usessl = true to usessl = false
reason: according to the requirements of MySQL 5.5.45 +, 5.6.26 + and 5.7.6 +, for data security and maintenance, if you do not set explicit options, you must establish a default SSL connection (true), change it to false and turn it off

[Solved] Java.lang.BootstrapMethodError: call site initialization exception

Causes of the problem:

When we upgrade the version of the company’s Flink, we type the task into a jar package and send it to the Flink cluster to run. Due to the upgrade of the version of the Flink, it has a certain impact on the components.

Question:

When collecting data, ES reported the following error
java.lang.bootstrap method error: call site initialization exception
java.lang.invoke.lambdaconversionexception: invalid receiver type interface org.apache.http.header; not a subtype of implementation type interface org.apache.http.NameValuePair

bug-fix：

In the POM file, HttpCore and httpclient are introduced separately, and then conflicting dependencies are excluded in the introduction of ES. However, this method does not solve my problem. Finally, it is solved by reducing the version of ES dependency, which is reduced from es7.11.1 to es7.2.0.

[Solved] Java.util.linkedhashmap cannot be cast to entity class

Solve the problem of java.util.linkedhashmap cannot be cast to entity class

Background description

When learning about grain mall, openfeign is used for remote call, because an interface returns R < List<· Object>> Type of data, using list <Object> When receiving data, the java.util.linkedhashmap cannot be cast to XXX data conversion exception error occurs. It can be seen that the remote call will convert the data to be converted to LinkedHashMap, but it will not work to convert it to the desired data type.

Solution one

Use typereference in fastjson tool provided by Alibaba to transform.

We add SetData () and GetData () methods to R. when getting data, we use typereference class to indicate the data type. Then convert the map to the JSON string, and then convert the JSON string to the data type we want.

public class R extends HashMap<String, Object> {
	private static final long serialVersionUID = 1L;

	public R setData(Object data){
		put("data",data);
		return this;
	}

	//Reversal with fastjson
	public <T> T getData(TypeReference<T> typeReference){
		Object data = get("data");//Default is map type
		if(Objects.isNull(data)){
			return null;
		}
		String s = JSON.toJSONString(data);
		T t = JSON.parseObject("",typeReference);
		return t;
	}

Caller

        R r = wareFeignService.getSkusHasStock(skuIdList);//Remote calls
        TypeReference<List<SkuHasStockVo>> typeReference = new TypeReference<List<SkuHasStockVo>>() {
        };// Declare the internal class, specifying the type
        List<SkuHasStockVo> data = r.getData(typeReference);//get data for remote calls

reflection

This problem also occurred when using resttemplate remote call before. This problem was solved before, and the solution steps were not recorded. This time, the solution steps will be recorded to prevent the next step.

Supplementary solution 2

Recently, when reviewing the previous project code, I found a similar problem when using resttemplate remote call mentioned in my thinking. The solution at the time was this.

	import com.alibaba.fastjson.JSON;
	import com.alibaba.fastjson.JSONObject;
	
	//remote call, return the specified collection, but this collection can not be used directly, because he is a LinkedHashMap.
	List<InnerControl> remoteList = restTemplate.getForObject("url", List.class);
	remoteList = transToList(remoteList);// After the conversion, you will be able to use this collection normally.
	
	// Define a method to convert the LinkedHashMap type to the data type we want
	private List<InnerControl> transToList(List<InnerControl> list){
		String jsonStr = JSON.toJSONString(list);//still use the json conversion tool provided by alibaba.
		return JSONObject.parseArray(jsonStr, InnerControl.class);
	}

IDEA springboot can recognize POM files, but suddenly it can’t reference mven dependencies. Strange things, inexplicable solutions

Foreword: today I open idea 2020.3 and find that all the spring boot projects can’t find all the dependencies. These projects were started normally yesterday

then I subconsciously thought that my Maven settings were wrong, but I checked and found that there was no problem with Maven configuration, and idea also recognized the pom.xml file. After reloading Maven dependencies several times, it still couldn’t work. Emmmmm, I think it may be caused by idea cache, right?The entire project was reloaded, but still not. Then I went to Baidu. There were not many solutions on Baidu and what I did above. I put on a mask of pain. I’m just a rookie. How can I meet this kind of thing?T.T.

Suddenly, I noticed that the red dot of idea event log was flashing, and I click to see

It said that there was something wrong with my plug-in, emmmmm. I don’t know why it suddenly went wrong, so I unloaded the plug-in, restarted the idea, and returned to normal. My God, what’s the situation?

[Solved] Java Error: Must declare a named package because this compilation unit is associated to the named module

Using the latest version of eclipse, you may encounter such a problem (error report)

“Must declare a named package because this compilation unit is associated to the named module ‘xxx'”
the reason for this is that in the latest version of eclipse, the package needs to be defined while defining a class.

How to define a package:

In the eclipse menu bar, select File – & gt; New-> Class command, in the Import dialog box, find the package, and then name it（ The position of the red line cannot be empty)

Solution: 1. Open the command prompt 2 as an administrator
         , enter netsh winsock reset  
         3 , and restart the computer.

Winsock is a Windows network programming interface. Winsock works at the application layer. It provides a high-level data transmission programming interface that has nothing to do with the underlying transmission protocol. Netsh winsock reset restores it to the default state.

Information:Using javac 1.7.0_79 to compile java sources
Information:java: javacTask: Source distribution 1.6 requires target distribution 1.6
Information:java: Errors occurred while compiling module 'MyThrift'
Information:Module "MyThrift" was fully rebuilt due to project configuration/dependencies changes
Information:2015/8/27 10:43 - Compilation completed with 1 error and 0 warnings in 4s 240ms
Error:java: Compilation failed: internal java compiler error

The solution is very simple: File–>Setting…–>Build,Execution,Deployment–>Compiler–>Java Compiler

Set the appropriate version of the target bytecode version of the corresponding Module (consistent with your jkd version), here I changed it to version 1.7.
